This is the 3rd air filter that I have purchased for 3 different vehicles. Each has met or exceeded my expectations.
Perry Zukowski, Libertyville, Illinois
I replaced my factory filter with the K&N as soon as a purchased the car! Very easy to replace and I know that my car will appreciate the improved airflow!
Athul, Kitchener, Canada
Fit fine, but a little more loose than stock filter on my 2013 A4 quattro. I would recommend this.
