FigJam-OhNine Posted March 26, 2015 Share Posted March 26, 2015 GYTR and K&N (possibly others) make a high flow air filter for the FJ. Anyone have experience with them on this bike or others? Does it make a difference? I figure you probably have to remove the gas tank to install it, but I've not seen a how to on that yet, so is it tough?

vespadaddy Posted March 26, 2015 Share Posted March 26, 2015 This would be a great topic for one of the tuning shops to post on. It would be great to know if the hi-flow air filter is good for any substantial power gain, as verified on a dyno. Link to comment Share on other sites More sharing options...

No powergain on the FZ-09, it has been tested and the stock FZ-09 airfilter flows alot of air. FJ-09, same engine, but ya could have a different filter. Not sure.

So, sounds like it's more of a placebo pill than a useful upgrade Thanks @cruizin FJ-09.org - Navigating FJ owners through marketing BS since 2014 Link to comment Share on other sites More sharing options...
Premium Member wessie Posted March 26, 2015 Premium Member Share Posted March 26, 2015 I would think you would need to get the ECU remapped to remove the restrictions you are encumbered with in North America before this would have any useful effect.

vespadaddy Posted March 26, 2015 Share Posted March 26, 2015 Hmm. From what I have read the USA-spec ECU softens power in the top 3 gears, so IF there is a power gain from this filter, it should show up in the bottom 3 gears, no? Link to comment Share on other sites More sharing options...

No gain on the FZ-09, with the same basic motor and filter as the FJ? *Boom* this forum membership just paid for itself with the cost savings!

papifun Posted March 28, 2015 Share Posted March 28, 2015 only difference is the K&N you can clean and reuse and the stock filter, discard and replace. I have also read on a DYNO, there are no real power gains. Link to comment Share on other sites More sharing options...
bobdog Posted April 1, 2015 Share Posted April 1, 2015 Yamaha makes a hi-flo filter for it too. Seems to produce a little more intake sound and that's about it.

Tricked the ECU into thinking (electronically) that it was always in the most powerfully-tuned gear, no matter what mechanical gear you were in. Woke it right up. Full power in any gear.

yamaham Posted April 2, 2015 Share Posted April 2, 2015 Try researching the net about disadvantage of high air flow filters...................more contamination passes the filter and enters engine. If you live in dusty areas or ride in such environment beware. Is the power gain (?) worth dust getting sucked in the engine. Unless you are racing and every second counts I would not bother.

phishfood Posted June 6, 2017 Share Posted June 6, 2017 My biggest question for the Fj intake is the air box. It has an odd intake location. Is the Fz the same with the oval hole on top? Seems like another baffle. Any mods to the box? Link to comment Share on other sites More sharing options...
norcal616 Posted June 6, 2017 Share Posted June 6, 2017 Both the FZ and FJ share same airbox...FZ-09 forum did some test and serious mods to airbox thats its not even worth the effort for such a small gain and the cost of getting a fuel controller is needed...stock airbox is excellent unless you are going the turbo route... 2012 wr250f - C-class 30+ age group 2015 fz-07- Hordpower Edition-80whp 2015 fj-09- Graves Exhaust w/Woolich tune by 2WDW @120whp Link to comment Share on other sites More sharing options...
koth442 Posted June 6, 2017 Share Posted June 6, 2017 Designing a well tuned air box means maximizing air density. That kind of math is similar to designing a shape in a musical instrument or a speaker. The air must behave as designed to create the proper sound. Since Yamaha also makes musical instruments and speakers, I also trust them to design an excellent air box. '15 FJ09 Link to comment Share on other sites More sharing options...
xlxr Posted June 7, 2017 Share Posted June 7, 2017 There are other threads reporting that removing the foam that is on the bottom of the gas tank improves air flow and gives 3 to 4 extra hp at higher rpms. If that foam is the restrictive factor, maybe a high flo air filter would help more if the foam is removed. Link to comment Share on other sites More sharing options...
