K&N air filters are great and I do recommend them. I put one in my Mustang and you can feel the engine breathing better and more efficient performance and acceleration. Get one.

I can feel the difference - every sports car owner should get a K&N filter.

I'm using the K&N drop in filter in my 2015 Mustang GT. I notice a better engine sound and the electronic average mpg meter reads 2-3 mpg better now. I was really surprised because I normally go full on cold air intake versus drop in, but money is tight at the moment. Also the stock filter that I removed was about an inch thicker and made of cheap looking paper, so I'm sure that wasn't good for air flow and gas mileage. I've always used K&N for my cars (normal street driving) with no issues. Be careful not to over oil when cleaning them. If you do over oil - let the filter sit and drain somewhere before re-installing. Thanks K&N for a great product.
