Great throttle response noticed instantly! Using it in my 2015 Mustang GT, its like I have the mode switched over to Sport +, and when I do switch it to Sport +, its has even greater throttle response and power. Great Job!

Love this air filter. Should come stock on all Mustangs. I can tell a difference in acceleration and sound from the engine. Highly recommend

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.
