K&N E-0647 Air Filter Product Reviews

Tuesday, June 19, 2018 - Part E-0647
I am a long-time customer of K&N air filters I put them in every car that I owned for the last 18 years.. this time I purchased a filter for a 2018 Audi a5 Sportsback... and this is the first time that the filter is not an exact fit ... there is a little clip that is supposed to lock the filter into place and the K&N air filter is maybe a half an inch short I had to improvise with a zip tie.
