DJ Ehrlich, Rincon, Georgia
I have always been pleased with K&N products, for my vehicles. I have not been able to make the 1 Mil. mile claim yet, but I'm working on it. I would like to see more products for foreign made auto models, such as Audi, Mercedes Benz, etc. Such things as Cold Air Intake Systems, not just filters.

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.

The installation was fairly easy, and the instructions were helpful. I still have to observe if fuel efficiency improved as time goes by. I noticed improved pick up during acceleration which was very pleasing. My only complain is that the threads on the filter bolts stripped very easy. I believe I may have stripped the threads on one of them when I tightened it, and I wasn't even applying too much pressure. I just hope it doesn't loosen to the point of disconnection.
