True, thats what K&N dyno'd it at, but you won't see 6-7 rwhp in real situations.
K&N dyno'd my FIPK at 12.98 RWHP @ 4801 RPM.

There is NO WAY it added 13 rwhp, and I didn't expect it to. I expected a cheap 4-5 hp, and a cleaned-up engine bay, which I got.
I'm sure they had the hood up indoors, cool fans going, and compared it to a dirty filter element, as well as many other things to pad thier numbers to better market thier product when it was "tested."
