To be honest, the installation was easy. Fits as good as the stock filter. I didnt notice any change in performance.

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.

Very good air filter. Had similar product in two BMW M3s in the past. Highly recommend them. Not sure if it increases HP but they are easy to clean and last a long time.
