2025 Chevrolet Silverado 3500 HD Engine Cold Air Intakes

This K&N NextGen cold air intake system is engineered for Chevrolet Silverado 2500/3500 HD V8 6.6L F/I. A high-density polyethylene (HDPE) rotationally molded tube helps increase the volume of airflow by 83.2% to your engine and provides an increase of 20.56 horsepower and 28.1 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. 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.
