Steve Mccully, Norwich, United Kingdom
Good service - and a good product.
Danny Niner, Laurel, Maryland
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.
Daryl Glindemann, Brisbane, Australia
Fast delivery and easy to install. Certainly makes a difference.
