I have used K&N on all my cars both drivers and performance cars such as 911 Turbo, MB AMG, Vette Z06, Viper,Hot Rods, as well as all my Harleys. I"ve never ever had any issues with their products. Per the Dyno K&N HP/TORQ are right on or over the published numbers.I never even look at other filters K&N has never let me down. Ted

Definite, noticible increase in output from '07 BMW X3 w. 6spd manual. Installation a bit frustrating because depth of K&N sealing surface seemed greater (or firmer) than stock filter making refitting cover a challenge. It certainly won't leak around edges now, however. Obviously a very simple and cheap way to gain some extra HP.

Best airfilter on the market.
