This K&N cold air intake system is engineered for your Ram 2500/3500 L6-6.7L DSL. A high-density polyethylene (HDPE) rotationally molded tube helps increase the volume of airflow to your engine and provides a guaranteed increase of 16.5 horsepower and 44 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 enclosed 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.
