Fast shipping. Easy instillation. Great performance
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.

Brilliant filter, has really improved performance, not massively, but there’s less lag, and slightly more power. More speed out of the revs. Has a healthy grunt too. The only thing I would say is I used to fill up around £50-60 a week, I’m now filling up around £60-70 a week, so the car is now a little thirstier, but that’s expected from a 3 litre V6. Thank you K&N. Love the air filter and the gains.
