      Exceptional Filtration. The K&N Series 57 FIPK Cold Air Intake is made of 4 to 6 layers of cotton filter media layered with mesh screens and specially made filter oil for better tack. This makes sure the filter’s microscopic fibers prevents dirt and contaminants from entering your engine.

      Efficient Installation. The K&N Series 57 FIPK Cold Air Intake is made to easily fit in your Sierra using basic hand tools. Hardware and instructions are included for flawless installation.

      Limited Warranty for 1 Million Miles/10 Years. The K&N Series 57 FIPK Cold Air Intake is covered by a limited 10-year or Million-Mile warranty.
