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.

Just bought a 2015 Mustang and as with all my cars and trucks the first thing I replace is that cheap factory air filter with a K&N. The price was right and delivery was prompt.
