K&N Air Filters are engineered to provide state-of-the-art performance and durability. The advanced air filter media is designed to increase horsepower and acceleration, as well as improve overall engine performance. The filters are constructed using premium materials and cutting-edge manufacturing techniques, ensuring a lifetime of reliable service.

These air filters feature four layers of premium cotton gauze treated with a specially-designed tacking agent, creating an intricate mesh that effectively 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 annual mileage of 15,000 miles.

Investing in a reusable K&N air filter can save you up to $125 compared to purchasing multiple disposable filters over the course of 200,000 miles of highway driving. Additionally, the no-hassle lifetime limited warranty on these stock replacement filters provides peace of mind and long-term value.

The K&N Air Filters are renowned for their easy installation, as they arrive pre-oiled and ready to be dropped directly into the factory air box. This simple upgrade is one of the most cost-effective ways to achieve quick performance gains for your vehicle.

By choosing a reusable air filter, you can help reduce the waste generated by disposable filters and their packaging, which annually accumulate in landfills. K&N Air Filters are proudly made in the USA, ensuring trusted quality and reliability.
