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.

K & N Filters are the best. I have them in all my vehicles except one, 2011 BMW X-5. I guess they don't have one for it yet. I have been using K & N filters for about 16 yrs now. I won't use anything else.
