This K&N NextGen Aluminum cold air intake system is engineered for your GMC/Chevrolet Sierra/Silverado 2500HD/3500HD V8 6.6L F/I. An American 6063 aluminum rigid tube helps increase the volume of airflow up to 41% to your engine and provides an increase up to 13.8 horsepower and 16.1 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.
