Over all I am satisfied with my K & N filter. I have replaced my stock filter with the K & N on every performance vehicle I have ever owned. Not sure if it has done a whole lot in the performance department, since I am not conducting any 1/4 mile speed runs, but when I get into the throttle I can now here my turbo spooling up. If I am getting more air flow I can't see it being nothing but an improvement with the turbo.
