the 10 hp caim from some magazine i was reading, cant remember which one it was, but it claimed up to 10hp gain. and as far as liking to see the dyno slips that document the hp differences you can request them from the K&N company.

Hi chris:

Oh, I see. It's that old "Up to.............." line of B.S. in advertizing. Which really means "anything from LESS H.P. to MAYBE more 10 H.P. IF the Stars and the planets are all aligned correctly, it's a leap year, and you have a lucky rabbit's foot keychain."

I have a K&N in my Z and I like it, I can really HEAR the induction system work when I stomp the go pedal. I think they make pretty good stuff, but there isn't any way I can believe the 10 H.P claim

def a great article. i personally use k&ns; it certainly FEELS more powerful, but the seatofthepants dyno isn't always correct....

Here is the simple fact short and sweet, it does flow a little more air then conventional filters. Another thing with these being K&N at least, you will buy only one filter ever.

If you change your air filter regularly like you are supposed to, every 3rd oil change, you will save in the long run by purchasing one now.
