This K&N NextGen cold air intake system is engineered for CHEV. SILVERADO 1500; V8-5.3/6.2L F/I. A high-density polyethylene (HDPE) rotationally molded tube helps increase the volume of airflow by 30.8% to your engine and provides an increase of 19.07 horsepower and 19.37 torque with no tune required. This intake system is paired with a washable, reusable High-Flow LIFETIME Air Filter™ featuring oiled cotton filter media. The oversized, conical design allows you to go up to 100,000 miles between filter services under normal highway driving conditions.
