Product was exactly as advertised. Perfect fit, easy installation!!! Not sure if horsepower was increased, but engine response is much quicker with a noticeable mpg increase! !!

Installation in my Audi S4 went very smoothly. Only irritation was getting the old filter out of the housing as it did not want to come out easily. I have not driven the car enough yet to see any impact on fuel mileage. I have seen a 1-2 mpg improvement in my other vehicles when I installed the K&N.

Awesome filter in my S5 with Stage 1+ 2, with supercharger pulley upgrade, made a big difference in air flow to the supercharger in low and high speed acceleration.
