Product details
This K&N NextGen cold air intake system is engineered for your RAM 1500 V8-5.7L F/I. A high-density polyethylene (HDPE) rotationally molded tube helps increase the volume of airflow by 36.51% to your engine and provides an increase of 19.94 horsepower and 19.93 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.
