This filter took all of 2 minutes to change and of course fit perfectly. I have used your filters on various vehicles in the past and currently have your intake system on my 2007 Harley Super Glide and also a replacement filter in our 2003 GMC Dually with a 8.1 liter engine. I think K&N filters are the gold standard for filters and am looking forward in the future when all of my vehicles have K&N air intake systems on them. Thank You.

Haven't had the filter installed long enough to rate it. Had a difficult time installing the filter. Could not find a small enough socket, (9/32), in the hardware or automotive locally to separate the air box from the intake. Ended up using an old socket from an old set my brother had. My car is a 2015 Chevy SS (Holden Commodore).

Purchased this air filter for my 2016 SSV. Absolutely fantastic, the performance increase and quality is amazing.
