The filter for my car $25 every 10,000 miles. Using this saves you that cost and run just as good as the OEM.

Great product and great service

After installing the K&N air filter in my range rover I immediately saw improved torque and can actually feel that the engine is freer breathing. Have not noticed any appreciable gain in mileage yet, but it's only been a week and all city driving

Best Aftermarket Filter
