Gotta ask....Are you equating a K&N air filter with increased performance? If so, why? I thought that the independent studies on reduced filtration efficiency pretty much relegated them to the status of a cosmetic upgrade.

The only one that I've found in the U.S. is the G-Power SuperCharger HP is increased from 355 to 450.

But the whole "performance upgrade" market is one of satisfying males' desires to spend money to make them feel good about their car. Tangible performance gains are secondary considerations in this market. |

Performance can be quantified, there are machines built for that purpose. But yes, I agree, K&N air filter gains are negligible at best. However, tangible performance gains are primary considerations for companies that make real performance parts. K&N air filters and aftermarket mufflers do not qualify as performance parts.... they might make the car "sound" faster. In that respect, you're right about the market for "those" companies.
