"I should have made this purchase 1 year ago when I purchased my Ford V10 Super Duty.I simply replaced the filter a week ago, took the vehicle on a 200 mile day trip and realized a mile per gallon gain in my mileage. It will be interesting to see the long term gains with this filter. It will only take 6 to 7 fillups of fuel to break even on the cost of the filter @ 4 bucks a gallon. My son just ordered a K&N intake system for his 2012 Camaro. Great company with great products." —Donald G from Clarence, NY bought a K&N Air Filters for a 2004 Ford F-250.
