Does anyone out there have a K&N power kit on there AC ? well ,does it really give it 15% more horsepower?is it worth the price? thanx

 

I have it on my 2000 500, As for 15% gains,,,I dont see it, But it sure makes the quad start and idle better, you can also tell a diffrence in throttle response. In my opnion and in the opnion at highlifter the pipe makes the most gain, if you installed a K%N + Jets + Supertrapp IDS2 you would see at least that much gain.
I run K&N filters on all my vehicles and love then they seem to be better about filtering out dust and you never have to replace them.
