Ok, so for those of you with the K&N Gen II Air Intake Kit, how noticable is the difference? On a dyno, how do the numbers come out?
Also, I know it's good, but it's damn expensive. Are there any other kits that are just as good or almost as good for less?

airaid is about $130..but you don't get all the equipment that K&N comes with...but it still has noticible difference...it is what I have, but I also made the heat shield to go with it.

i thnink if you have a 4cyl it is harder to tell a difference, i know in my v6 when i put my k&n gen 2 on it i could tell a hell of difference!

i did the gen II and headers at the same time. couldn't say which was better.but together they made a real big difference.

What ever you decide, do your self a favor and wrap the
tubing with a good heat insulation wrap, it will keep the air
temp going into the motor cooler:thumbup: Better for making
HP I checked mine with a scanner the cooler air raised the
A/F RATIO.
