I don't have a K & N on yet, but do have a Conical high flow air filter (that I am about to replace with a Round Tapered K & N). I didn't notice a huge gain, but in the higher RPM ranges, it does feel a little more peppy, and definitely has an aggressive "roar" sound, again at higher RPM's.

I know that it is letting in more airflow, as the computer had to readjust to the new intake. But as for many people's claims of huge 20 hp gains from an intake, I don't think that is realistic.
