"After I replaced the OEM air filter with a K&N filter in 2001 Mustang GT convertible, rpms at 60mph dropped from 1750 to 1700. At 65mph, rpms dropped from 2000 to 1900. Clearly the engine is delivering more power. Judging from what the car's previous owner told me, mileage also improved 1/2 to 1 mpg. Fortunately, the K&N only slightly sharpened the sound of those beautifully tuned factory dual exhausts -- and added a bit of back-pressure rumble while decelerating. Nice." —Blair B from Buffalo, NY bought a K&N Air Filters for a 2001 Ford Mustang.
