Michael , South Dakota
I have always owned a K&N air filter for my various vehicles. From my truck to my car the K&N air filter provides high quality performance in any weather that is thrown at it. I live where all four seasons storm through each year and through the snow, rain, dust, and gravel roads my K&N filter has never let me down. Maintenance is simple and quick.
