This K&N NextGen cold air intake system is engineered for Chevrolet Silverado 1500 V8 5.3L/6.2L. A high-density polyethylene (HDPE) rotationally molded tube helps increase the volume of airflow by 35% CFM GAIN to your engine and provides an increase of 10.4 horsepower and 10.9 torque with no tune required. This intake system is paired with a washable, reusable Dryflow LIFETIME Air Filter featuring an oil-free synthetic media. The oversized, conical design allows you to go up to 50,000 miles between filter services under normal highway driving conditions and has an easy oil-free two step cleaning process for convenience. A custom designed NextGen air box helps protect intake air from the high temperature of your engine bay, and the entire system can typically be installed in less than 60 minutes.
