I have been using K&N air & oil filters for over 25 years and after installing the air filter in my new 2015 mustang which only took five minutes and fit perfetley I did notice a slight improvement in performance. I recommend all K&N products.

Fits perfect, easy install and as is the case with all my previous K&N filters, works great.
Chris, Florida
Excellent product as always with K&N. I wasn't ready to invest in a full on CAI for my '15 EcoBoost Mustang, so I went with the drop in filter instead. Can definitely notice a more responsive throttle and quicker boost build. Extremely fun to drive in Sport Mode.
