I’ve been a believer of K&N filters. Use them on my cars and motorcycles. This particular filter I ordered is for my 2016 Shelby GT350 and it was easy to install, less than half a minute to install. Perfect fit and didn’t require any tuning.

I have run K&N on all my cars. From sedans to Porsches, Ferrari, and my track cars like this GT350R. Same solid quality I have come to expect from K&N.
