The K&N air filters are engineered with state-of-the-art air filter media designed to increase horsepower and acceleration, as well as improve overall engine performance. They are manufactured with durable, premium materials and advanced construction methods to last a lifetime. The filters feature four layers of premium cotton gauze treated with a specially-designed tacking agent, creating an intricate mesh that blocks and traps harmful contaminants.

Under normal highway driving conditions, the engine air filter only needs cleaning every 75,000 miles or approximately 5 years, based on the average of 15,000 miles driven per year. This reusable K&N filter can save you up to $125 compared to purchasing multiple disposable filters (based on MSRP of corresponding OE filters for 200,000 miles of highway driving). K&N air filters also come with a no-hassle lifetime limited warranty.

The installation of K&N air filters is easy, as they are pre-oiled and ready to drop into the factory air box, making them one of the most cost-effective vehicle upgrades for quick performance gains. By using reusable filters, you can also help reduce the waste of over 200 million disposable air filters and their packaging that end up in landfills each year. K&N air filters are proudly made in the USA, ensuring trusted quality and reliability.
