K&N Performance Air Intake Kit for 1999-2004 Chevy Silverado/GMC Sierra 1500 (V8-4.8L / 5.3L) 57-3021-1

Fits 1999-2004 Chevrolet Silverado 1500 and GMC Sierra 1500 (V8-4.8L / 5.3L).

The K&N 57-3021-1 Performance Air Intake System is engineered to reduce intake restriction and improve airflow to your engine. By replacing the restrictive factory air path with a rotationally-molded high-density polyethylene (HDPE) tube, this system provides a larger volume of air than the stock assembly. It features an oversized, conical High-Flow Air Filter with oiled cotton media, designed to provide excellent filtration and high airflow while lasting up to 100,000 miles between services under normal highway conditions.

This kit includes a custom heat shield to help isolate the intake air from high engine bay temperatures. Designed for a straightforward installation, the entire system can typically be bolted on in less than 90 minutes using common hand tools.

• Increased Airflow: Rotationally-molded HDPE tube increases air volume to the engine.
• Premium Filtration: Includes a washable, reusable oiled cotton High-Flow Air Filter.
• Heat Management: Integrated heat shield protects the air filter from engine heat.
• Long Service Life: Filter can go up to 100,000 miles before cleaning is required.
• Warranty: Backed by the K&N Million Mile Limited Warranty.
• MPN: 57-3021-1

Note: Some intakes are not legal for sale or use on pollution-controlled motor vehicles in California. Please check the CARB status for your specific vehicle before purchasing.
