K&N 33-2128 Air Filter Product Reviews

Wednesday, September 7, 2016 - Part 33-2128
I have used K&N air filters on my last 3 cars, so I must like them and trust that they will clean air for a long, long time. Only thing I'd like is for K&N to include a sticker that allows me to write down the date/mileage near the K&N sticker. What I've been doing is attaching a paper tape to enter the mileage and covering that with a clear plastic tape.

I've run your filters in everything I've ever owned. From my 2009 Ford Fusion, my 2002 VW Beetle, 2003 Honda Goldwing, and my 8 sec, 155 mph 79 Mustang drag car. K+N filters rock!!

The air filter is so much better than the standard air filter I had fitted. My Audi TT seems quicker and more responsive. I would also like to add, the gent I spoke to over the phone was very professional, helpful and well spoken which made a nice change. If I could I would of given K&N 6 stars. I am also very happy to not have to buy another air filter for my car.
