I've witnessed K&N's on the dyno, with different types of engines. (4-8 cly's.) Sorry, NO gain. zero, zilch, nada...Add the factor that just a little too much oil can wreak havoc with the MAF.
Think about it...you can by a lot of paper for the price of one K&N and cleaning kit, with the same hp and torque and no worries...

PS...not to crtitcize your purchase Riddler..(looks like you just got one) It sure wont hurt, as long as you watch the oil volume.

 

There is a gain, there cant not be. Anytime u are flowing more air into the engine, u are going to add hp, theres no 2 ways about it. With my k&n and custom airbow, i saw gains, with my ko4 setup, thats just all there is to it. There might not be much hp gains, but def better throttle repsonse, and prolly around 3hp.

 

ya i agree with you audiboy, im off to the volkswagen dealership today to buy a 710N diverter valve and then sometime next week im gonna go over to greed speed, and buy there snub mount.

 

I am not a fan of K&N at all. I use an Apexi cone filter when I can. They are rated to flow better and filter better than anything I have seen.
