K&N air filters are made of 4 to 6 layers of cotton gauze sandwiched between two epoxy-coated aluminum wire screens. The cotton is treated with a specially formulated grade of oil causing tackiness throughout the cotton's microscopic strands. The nature of the cotton allows high volumes of air flow. When this is combined with the tackiness of the oil it creates a powerful filtering media that ensures engine protection.
K&N air filters are engineered to fit directly into the factory air box, no cutting or fitting is required. A support plate is included with the 33-2397 to ensure a positive seal in the airbox. It is important to ensure the K&N filter and support plate are seated together for proper installation.
All K&N air filters are washable and reusable and filters for street vehicles are backed by the famous K&N Million Mile Limited Warranty. It will be the last air filter your vehicle will ever need.
