I use K&N in everything I own, three Harley motorcycles and three Audi cars. The improved air flow rate instantly gives a kick where you really need it, acceleration

Filter is doing a good job with some noticable increase in power / acceration and on some small, but positive increase in gas mileage. However, the QC on the product was a little below standard with some large excess plastic / rubber on the filter top where it seals with the top of the air filter housing. Appears not to be a problem, but y'all should notice these things in production as a mold or something is our of line.
