Hi all,
My GSX14 has been back firing a fair bit recently though does sound good :devil: Also noticing performance isn't what it used to be. Wondering if this could be down to the air filter and I've done over the service interval millage so figured I'm going to replace air filter, do a much needed oil and filter change which I've kept putting off due to weather being crap and also to replace spark plugs as I'm sure I've done over the millage for them now as well lol.
I looked on wemoto for air filters and there's a HIFLO filter, K&N performance and a Simota performance air filter. I've heard K&N filter restricts the air flow more than the OEM one so just want some info on what filter to get or if anyone has any recommendations?
Save your money and buy OEM :smile2:
OEM.
OEM :hat:
I agree OEM .... and as a matter of corse if your ever in doubt about anything on your bike go OEM you wont go far wrong :onya:
I say that about exhausts !!
:stir:
OEM, $120 in Oz.i buy these from Poland. perfect quality. now says he doesnt post here, he will. 6 for the price of one OEM. waste of money buying Suxuki gen. https://www.ebay.com.au/itm/KR-Luftfilter-Air-filter-SUZUKI-GSX-1400-GSX1400-02-07-/160880859473?pt=DE_Motorradteile&hash=item25753f1951
I have a HiFlo on mine and it works perfectly, no difference in performance but cheaper.
The original OME filters had a slightly bigger inlet and flowed more air but the suzuki ones you get now are no better or worse than any other air filter so any is ok .
K&n are re-useable if you clean them .
I use hiflo filter in the14's that have airbox's as cheap and work just fine.
:cheers:
I miss the proper OEM ones, I can feel the difference with slightly worse pick up and MPG since I changed mine out. It'd done about 50k so it was rather overdue & had gone rusty.
I use a Jap Simota filter, but I also have a full yoshi ststem.
I replace my Hiflo to Suzuki OEM.
Hiflo intake is 39mm, OEM intake is 48mm - it's area is 34% bigger than hiflo one. Also it's slightly higher - also easy to get air throw.
Local prices are ~25€ for Hiflo and 35€ for oem, so my choice from now on is Suzuki OEM.
@northern , If you test those two filters you can feel the bigger intake hole at higher revs, the same happened to me, when I girnded bigger and smoothened the intake hole of my K&N. It was 48 to 54 mm if I can remember correct. That is why the OEM filter is faster.
Thank you
@northern for measuring. The added "inner tubing" on the hiflo can't be good either. I don't know where the original test data is, but I have read several times that a dyno test (on a 14) was done with OEM vs various aftermarkets.
So which do i get, im all for bigger inlet. New oem have smaller inlet, i measured. Spend $200 on the japanese option? Will re measure my pure quality polish one. Yes Andre, they are good quality. 40 th ks, no probs. Bigger inlet option , tell me what to buy
@grog I certainly would not spend 125€ (200 Aus. $) on an airfilter. That's ridiculous!
I am certain northern has a new OEM and that has obviously a larger inlet than the Hiflo. Appears to me that many cheapos are patterned after the Hiflo (as per pics on the net). Maybe the inner tubing, which I think is restrictive, does just the opposite by increasing speed of airflow :confused1: (didn't study flow dynamics :bugga: ) Others here say that they work just fine.
@Hooli Didn't you modify the aftermarket (Hifo type?). What is the result, any improvement?
Anyone here have the measurement of the older OEM filters to compare to northerns's measurement?
Andre, really not concerned. My polish works fine.for stupid amount it cost, chaeap i mean, no prob. Has been to a one off brave night to 240. Ill just keep same. At my work we raplace at least 50 air filters a week, all diff brands, diff countries of making. Never had a failure. Only failure i can think of was kn, foam went thru turbo, destroyed turbo.

Somewhere on the old ORG I think.
@grog , Foam?? Isn't K&N made of cotton?
T24, yeah cotton. I think they have foam pre filters on some. Lots of reasons it couldve failed. Wrong oil, not fitted properly etc etc. i wouldnt blame the filter, they make millions of them. Good filters.
This talk about the OEM filter´s good features is true. Small increase in bellmouth´s size has a big impression for engine´s breath. I had a Bonneville SE some years ago and made a modification in that called "Polaris bellmouth-tune" From the first test run You felt the difference. Mod helped the engine to run more willingly. Some Bonneville users have measured hp after that tune and they claim that they got some hp more with that tune. Anyway the bike felt to run more freely. Any gear, any rpm.
I recommend also the OEM filter to GSX 1400. Why on earth to restrict air flow for some €:s cheaper air filter?
Quote from: Andre on Tuesday, 08 May 2018, 08:29 PM
@Hooli Didn't you modify the aftermarket (Hifo type?). What is the result, any improvement?
I did. It's much improved, not sure it's quite as good as a proper OEM filter but about 80% of the way there I'd say. No more strangled noise when opening the throttle & improved MPG to prove it's not being choked.
If the OEM ones coming out now are right I'll get one next time, last time I looked at anywhere it showed the K2 filter superseded by the later one which appeared smaller/more restrictive (I can't recall exactly) in the pics.
I just got caught out. HIFLO air filter has a lot smaller inlet. Back to the shop, order OEM. :thumbs_down:
Just ordered OEM filter and its $7.50 cheaper at $62.00.
I put a Hiflo in mine 6 months because of the stupid price of OEM over here, but can't say I noticed a difference. Maybe there is :confused1:
How did you mod yours Hooli?
Local Suzuki dealer wants $114.00 for OEM so l use a small Suzuki dealer an hour away. $62 + $9 courier.....job done.
What do you pay in Sydney Sweaty ?
I run a BMC in mine
From memory.....
The old org tests about the air filters was to show there was no improvement using the "performance " air filter over the genuine and OEM like most other bikes gain from the "performance" filters meaning the airbox on the 14 was designed very well
$56 here, priced oem just a while back. were $129 few years ago. mine from Poland, work perfectly, no one interested so never bothered again. $20 landed. same quality as oem i reckon. goes exact same, sounds same. if it looks like a duck, walks like a duck. we all know the answer.

A Polish Air Filter?
I've got some of them too, think I brought 4 a while ago. Seem fine to me too. Mind you, the black it's fitted in does have a 'sooty' looking can.
Col, dont blame the filter, ulp will do that. mines same, was with oem filter. 50 mpg, nothing wrong.

Grog, I did check the one you got (which is the same as the hiflo) but got one from wemoto for a few extra $ and quick delivery from memory.
Cheers for that Grog, Thought it was possibly running a bit rich & would get round to checking it at some stage. Maybe not now. :cheers:
I have a K&N and original and like Sweaty can't tell the difference.
I have piper cross only bcos I remember my ford Corsair had one on the 70's as they were considered top make - and they wer a lot cheaper :smile2: and I can't tell any different the way I ride :)
When I bought mine I never checked or asked, it wasn't till I pulled the tank off after about a month of riding that I saw it had a K&N fitted. I cleaned it (out of habit and cause I didn't know when it was done the last time) and reinstalled it. I've run K&N in my last two bikes and never had any problems, as long as you look after them and clean them regularly. I like them because they're reusable and cleanable.
So I have no other point of reference for this bike. To date hasn't missed a beat and at the moment I'm getting about 6.8l/100km at "normal" highway riding speeds. Would be interesting to find out the fuel economy others are getting using OEM filters.
Thinking about removing the air box altogether and fitting 4 separate pod filters (as posted elsewhere in this forum - just for the looks and the induction sound....
Last weekend on a 200+ mile trip I got 55mpg.
Thats riding alone at my own reasonable pace..
When I am with mates then that drops to around 49mpg on a run.
I am very happy with those figures for such a heavy beast...
Then there is the bike as well !
:grin:
Always used OEM air filters. On long trips and warm weather I have gotten as low as 5.05 liters/100 km (sorry metric guy here). Shorter trips I get 5.4 to 6.2 l/100 km depending on the throttle hand. Really gunning it with my 1st 14 I needed over 8 liters (these times are long gone). Hard to compare your consumption with others.
Agree that it's hard to compare, as everyone rides differently. It does seem that OEM or paper element filters may get better airflow, and I'm sure that some engineer at Suzuki at some stage spent some time designing the air box and air filter, so that cannot be discounted. I may try an oem filter at the next service interval to see if any difference.
My average is 6.23L/100K I've been as low as 5.4L/100 & as high as 6.9L/100
Andre, you must have some long flat highway riding and lots of traffic to get to 5.05, :whatever: but your 8 sounds quite manic! :onya:
not sure what to do, mine keeps using petrol.
Quote from: grog on Wednesday, 08 August 2018, 07:25 PM

:rofl2: :rofl2:
Tòok Hi Flo air filter back to bike shop today. Mechanic said l can see why you dont want it. Small inlet tube goes quite deep into the filter.
Suggested a K&N yet there are comments on here that the OEM filter flows more air. I do kinda like the idea of a servicable filter.
So you blokes say ??
My perspective... Suzuki designed that airbox for use with the standard filter. I don't think K&N adds anything in terms of performance, is expensive and has to be cleaned. I prefer to use a new oem filter every time I change - maybe slightly more expensive if compared over the lifetime of the K&N but at least I am guaranteed a clean filter every time.
Im sure others may have a different view - horses for courses and all that :cheers:

We do have long flat highways - we call Autobahn. I avoid them but when I do lots of petrol is used as there is often no speed limit. That's when I emulate you Anglo lefties by mostly staying in the left lane :happy1:
The low 5.05 came on a long sedate trip using the smallest roads I could find and traffic is light.
The time of the 8 was truly manic to put it mildly. I was a :devil: on my 1st 14. I still don't get it why I never got caught while giving bikers a bad name. :thumbs_down: :thumbs_down: :thumbs_down:
@ARH Thats my thinking too.
K&N for me, payed for its self 4 times over, not hard to clean and they definately catch dirt, I put the pic's on before to prove it. And as I said no difference worth even talking about. Even use them in my classic bikes.
totally understand Irish but i just like paper . my polish supplier wont post to oz anymore. i have to choose another. genuine is only $56, in stock at springwood suzuki, not in stock sunstate. where i live. if it has bigger intake, ill buy. any of you blokes in brisbane want to go check. havent checked other choices. i know jap seller has big inlet ones but nearly 200 bucks, stupid price. your advice welcome.
Grog, the K&N I pick up on special offer for $89 delivered.
http://gsx1400owners.org/forum/index.php?topic=1371.15
Irish, can buy a k&n out of a trashed 14, 30 th ks only. looks perfect. $60. cant have been in long if bike only 30ks. do it?will need your instructions on your way of cleaning. no oil you say, other places say it needs oil? thanks mate. same price as oem, ill take your reco. always been a paper type but old dogs can learn new tricks.
@grog Repco & Supercheap sell the cleaning kits & oil for K&N. They're a buy once item as you'd be hard pushed to use all the cleaner & spray oil in the kit, will last for years. Instructions on the pack.
so Col, buying a second hand air filter, makes me feel like im buying second hand dentures, cheapskate. it looks perfect, i just need backup. never tried k&n before. once had oiled foam on ducati, parked overnight, next morn his dog had eaten both. made his food slip down i guess. :)
Yeah but they're made to be re-used, over & over. It's not like you're buying a 2nd hand tyre that's ½ worn, these things come up like new, time & time again. Just don't let yer dog eat it over night! :happy1: Would be hard if it's installed anyway. :onya:
Col, i bought the K&N. ill get cleaning kit tomorrow. to clean, spray inside, wash out with hose? oil inside? never had a prob with polish paper filters but he wont post anymore to oz. ill measure air intake to see kn any bigger.
To re-oil, it's just a light spray till you get even coverage. It's not heavy oiling or dripping off or anything. Wait around 15-20 min for the oil to wick through the cotton & look for spots where it isn't an even colour, just touch up those bits & you're good to go.
Plenty of u-tube videos showing how to do it too.
my K&N arrived today. just like new.$61, my bargain of the week. ill measure air intake holes of oem, klaas racing, polish ive been using. and K&N. will i notice any difference, i doubt it. seller has crashed bike, ill try for a list of what else for sale. will post if anything interesting.
got cleaning/oiling kit today. will do it all tomorrow. e bay sure gives bargains sometimes. very happy.

You can grind the intake hole of K&N to 56 mm, and make it smoother. It helps a bit on higher revs.
I made that mod to my K&N, but it won't fit to my turbo set up, so if somebody needs it, I can sell it...
today, cleaned n lubed kn. longer bolts required to fit, monday job. no one told me that. biggest prob is i lost a washer off air filter. where it is, no idea. hoping not in airbox. will give inside of air box a good blast with air gun in morning. simplest job, nightmare. 51mm intake kn, other was 39. must flow better. really annoyed losing that washer. slap me please.

@grog have you not got one of those magnetic telescopic pickups, wave that around the bottom of the airbox and that would soon pick up the washer

I'm currently on holidays abroad, but will be soon back, so we can discuss details. P.M. me, if you interested.
Barmy, will do that as well as air blast. Think i have about 5 telescopic magnets. All shapes n sizes. Would love to find that washer but guessing its on garage floor somewhere.

Just seen this.
I can't recall if I drilled the four spot welds out or just sliced around it with a dremel.
this morn, got magnets, air blaster into air box. no sign of lost washer. found some longer bolts. K&N fitted. checked external fuel filter, all good, gave it a air blast. bike does sound slightly diff, imagination? 39mm intake now 51mm. free revved to around 6k, much quieter for sure.
Just to compare - K&N inlet is 56mm, versus OEM 48mm and Hiflo 39mm

The 56 mm is for the modified K&N according to T24. Grog reports 51 mm.
ouh....
You right
@Andre , I totally miss this. :doh:
51mm is standard k&n, might be out a bit. couple of weeks with it in. waiting your report Northern. i have one but will wait. i tried to work out area of intake between K&N, compared to hi flo/ klasa racing with smaller inlet.they also have metal tube that goes way down into filter. not sure why. my calculations, very rough, i think K&N has around 5x as much intake area. i promoted the klaas racing as very good, it was. i now have changed my mind. your report Northern then ill comment.
@grog So, I have done few hundred kilometers with new filter. What can I say - nothing. :)
Bike is fast and accelerates good. But is K&N better then OEM filter - really hard to say.
So my plans are - fix fueling, play with Autotune and POD-300, and at beginning next summer go to dyno, to compare OEM and modified K&N performance. But there is some time, before it happens. :hat:

Remember to fix fueling in both cases on dyno. I needed a bit more fuel with modified K&N on top end, but I don't have any dyno numbers concerning to that mod.
The difference isn't big, if there is any...
Am trying to help a friend who is modding a GSX 1100. He would like to know the physical diamentions of an OEM 1400 air filter.
Because I'm lazy l thought l'd ask before pulling mine out to measure it.
TIA.
OEM air filter dimensions
Bottom diameter: 8.5 cm
Height bottom to mounting plate: 13.5 cm
Mounting plate diameter: 10.3 cm
Mounting holes across ctc: 11 cm
Mounting holes next to each other ctc: 7.9 cm
Many thanks Andre :cheers:
Interesting update on this.
I'd noticed a slight flatspot around 3/4 throttle when running the hi-flo (should be called lo-flo with the tiny intake) so as an experiement I put back an original OEM filter that's done about 50k miles. That's the flat spot cured, the bike feels more responsive & isn't making as much intake noise so obviously isn't slightly strangled anymore.
Guess I'll have to get a real filter for it, as pattern ones are crap.
Whats 3/4 throttle ?
What are all those numbers that go higher than 4 on the right hand clock ?

:imrgreen:
What ya do Si, is get it into 3rd like normal, then when you're about to change into 4th, instead of throttle off & go up a gear, just crack the throttle right open :devil: (and hang on) :doh: & watch the wee right hand needle go to where it likes it :imrgreen: - 6's & 7's are it's favourite numbers . . .
:cruisin:
So used to driving a diesel car all day I rarely go over 4k rpm on 14...
Over a year now since K&N fitted. Bike runs perfectly, as it did wit OEM. The smaller intake one i had from Klauss in Poland was ok, I dont go for power but can definately notice perfect revs from start to finish. Also better fuel mileage, never measured but notice a few more ks between fills. Im a big fan of dry paper, so OEM is perfect. Just having to wash out K&N also suits me. Thats a big change for me, always liked dry paper. Things can change.

You've got the slower R&B model so it doesn't concern you....
I need to find a seller of a real air filter though, I might even ask the local dealer. Robinson's have superseded their part number to one that includes 'K+N' so I rather suspect it's not OEM.

Yeah but add it to your basket & go to the checkout & you get this.
:facepalm:
I've found them online for £24.50.
You can see it's a proper one as the trumpet doesn't extend inside the filter, every aftermarket one I've ever seen does.

Would you measure the opening when you get it Hooli? (and post here)
Might take to my aftermarket one with a dremmel cutoff disc & chop that internal piece out. The blue has a K&N fitted.

Thx Andre, I knew it was on here somewhere, it was a quick visit to the site while at work when I asked the question.
And yet my bike runs just fine with the HiFlo air filter fitted..
Mind you I dont tend to screw my bike everywhere I go so maybe thats the difference.

With the Hi-Flo, I don't think it affects whether the bike runs fine or not, more that it can restrict performance having the smaller intake.
My bike has always run perfectly with 3 diff types of filter.. Cant remember thoughts/sound on stock paper. When K&N fitted i could notice diff sound even though its a long way from ears.compared to smaller intake/tube down inside type. No testing but also think fuel mileage is better and revs easier above 6k. No test or figures to back up but quite happy with it.

From memory grog, when we 'tested' a stick and K&N on a dyno, the difference was negligible, the K&N gave 1 bhp less over stock. The view then was that unless you did high mileage, then probably the K&N wasn't worth the outlay over using a stick air filter, i.e for low mileage riders, there was no benefit to be gained from replacing a good standard stock filter. That was all.
Clearly for the high mileage boys, or those that live in dusty conditions, then being washable, there would be a cost benefit over the years.

Mine seemed to run fine, with a bit more induction noise when wound up to the bits of the rev counter you don't visit. But when tested on an unrestricted autobahn it was suffering a massive lack of top end...
My new filters turned up today (I ordered two) side by side with the original they are identical as you'd expect for something that came in a suzuki box.
Can you tell which is which?
it would have been hard for the girl to breathe through that black one.
Aye. The black one was taken out years ago, but kept to compare pattern ones too. I only refitted it last week as a test to prove it was the pattern one causing the issue.
Hi Guys my bike came with a K and N filter installed when i brought it and was one off the first things i got rid of when i serviced the bike , im 57 year old and have had road and dirt bikes all my life . i dont give too shits what they say about the fibers vitiation when the engine is running that makes K and N good. there is no performance gain and as for what is saved in re using the filter is lost in buying the product to service it, a total waste of time and money . unless your ridding down dirt roads stick to the factory paper element , i mean the boffins in japan worked all this out didn't they.
BTW have run K and N on a DRZ 400 and found fine particulate passing into carburetor body. on 2016 WR450 with foam oiled filter nothing.
in saying that back in the lat 80s i had a 900ss Ducati that had nothing but a belmouth on 40mm delortos carbs.
its where you ride and hat u suck in but i i will be happy to send anyone my near new K and N air filter if they want to pay the postage i dont want it.
for me its what that jap boffins worked out paper
The standard Suzuki air filter the bikes came with new flowed slightly more air than a K&N replacement( proved many years ago on a dyno) but it's probably the next best thing if you can get a Suzuki standard air filter.
Most pattern replacement air filters seam to flow much less air causing some folk to have issues with the bikes smooth running .
:cheers:
I have a K&N in mine and when I changed from standard I didn't notice any difference.
Jake, i had oil/foam on my 900 Duke back in 80s. Parked up o/ nite at mates place and his Blue Heeler ate them. Well lubed dog that one.
Standard every time for me - many years ago i tried K&N`s on my Z1. Disaster, couldn`t change back quick enough, they completely changed the power charcteristics of the engine - a significant loss of low down power, which is exactly where you want it!
DP, have had oem, klaas and K&N. Klass is like hi flow, top end less. Stupid tube down the guts. Cant tell diff between other 2. I agree paper is good, we fit to every car we service at work. Also K&N works for me. Service kit just $20, gives about 5 cleans & oils. Bike runs perfectly, all i need.
grog, good points.
I based my comment on personal experience many years ago. Its the old story i guess - if K&N`s were total rubbish, no-one would fit `em! They`re not for me thats all.
I really like `standard` personally - i base that view on the fact that Mr. Suzuki spent a long time and lots of dosh developing parts to give the `14 optimum `every day` performance, and i`m reluctant to mess with that!
So , if you owned a k7 youd still have bazooka fitted?
I stick to standard & change it every 50k miles if it needs it or not, just like the plugs. Works for me & the bike runs fine.

I have a K7, and it is totally stock except for the K&N which I reckon makes no difference, I also have Givi screen, rack and pannier brackets, but none of it seem to make it slower. Put a staintune on it but was too noisy was like riding without earplugs.
:hat:grog, doh! I think there`s little point in re-iterating what i`ve already explained earlier in this thread, but for the avoidance of doubt, if I had been lucky enough to purchase a K7 from new, then likely as not it would still be running with standard Suzuki replacement service parts...... :whistling:
Have had my beast nearly a month now . when I filled up with juice first time I put 95 in it which stopped all the popping ,spitting and farting !!! (the bike not me !)....I'm guessing must have been filled with 91 before ? So what do most people use ? petrol varies between countries etc too .
Anyway its going great ( has the tri oval Yoshie on it which they did here in NZ for the last few apparently ? Rego'd first here in 09 one of the last?).
@Roo Please head over to https://gsx1400owners.org/forum/index.php?topic=2701.0 (https://gsx1400owners.org/forum/index.php?topic=2701.0) to find answers to your question. This thread is here is about air filters. :grin:
Had a significant induction 'sucking' noise since I bought the bike. Not any more. Ordered a genuine filter for abut £37.
If anyone is interested what the pipe looks like on the non OEM filter:

Yup & even after removing that, the hole is still smaller. Plus the bike doesn't run as well as a genuine filter, at least mine doesn't. I assume it's because it's not a smoothed intake & restricts how well it breathes.

I guess that along with the intake hole size, the filter media might not be as free flowing in the third party filter.
You could be right. I'm going on the extra noise, which is normally a sign of restricted flow.
Anytime I had pods on a bike, my Katana with CR carbs there was increased noise that wasn't because of restriction in flow.
My RD400 runs standard and has high induction noise, don't think it's from low flow. So I suppose it works both ways.
True, but then you didn't have an airbox to hide the noise either so it would be louder.
I'm sure you know noise is vibration & the only way airflow will produce vibration is via turbulence, which will restrict flow.
I'm no expert on this though, I just know those aftermarket filters made my bike slow & thirsty. Taking the intake pipe out of them helped at low throttle/speeds but it still didn't run properly and it had a lot more induction noise in normal riding.
we need a turbo, that'll fix it
Pfft, only asthmatic engines need ventilators.

14 is badly asthmatic :devil:
Bought a Hi-Flo air filter a while ago. When l went to fit it l changed my mind and bought an OEM filter, which finished up being cheaper too :onya:
I still have the K&N in mine, and it hasn't been cleaned in over two years.
Irish, not allowed to mention them. Worm cans etc. You can guess what i use. 😎
Should I be ashamed of my K&N ? :bugga:
Yes :whistling:
Notty, no.

Grog if I remember correctly you got one after my recommendation, the K&N is the only modification on my bike. In 90,000 klm's I have only changed the oil filter and oil, plugs, tyres chain and sprockets,front discs, teas bag cleaned at 60,000, it has never had the rocker cover removed. In all this time I have never had a problem with it and never seen a F! F2 light. What am I doing wrong.
