K&N Air filter. 9 months 3 weeks ago #1

Servicing the bike next weekend, was wondering is it ok to put in a k&n air filter on to a stock bike, or just go with the standard yamaha filter?. Muchos Grassy-ass.	johnnywaite OFFLINE Junior Max Posts: 86 Thank you received: 65

Way back I think Tim Nash did a dyno test on the 2009 Vmax. If you put in the K&N filter and remove the restrictor plate behind it you gain something like 4 or 5 HP on a totally stock Vmax. Cheapest HP I know of for the Vmax... considering the Yamaha stock filter costs about the same as the K&N filter.

Correct me if I am wrong.

Here is a few links.

I looked for the dyno results but can't seem to find them.

I took the restricker "plate" out of my stock 10 and put a K & N in it at thunder this year and definitely noticed a differance!	twistedmax-gasser OFFLINE Senior Max Posts: 161 Thank you received: 117

K&N filter with restrictor plate removed stock bike , no problem will work fine. The stock fuel mapping from the ECU can compensate for the added air flow with no issue's. But if you really want to make the most of your stock bike get your ECU reflashed by TIM at guruedgear.com/index.php?dispatch=products.view&product_id=66 and your beast will be a hole new animal vmaxmercer	vmaxmercer OFFLINE Platinum Max Posts: 2565 Thank you received: 1029

I think someone else just recently asked this but do you need to remove the air box to remove the restrictor plate? and if so is it just a matter of removing some bolts.	doughboy OFFLINE Junior Max Posts: 75 Thank you received: 19

No just need to remove the entire top of the air box. Very easy just a lot of screws	Sgroves79 OFFLINE Senior Max Posts: 126 Thank you received: 120
