This K&N NextGen cold air intake system is engineered for Dodge RAM 1500 V8 5.7L F/I. A high-density polyethylene (HDPE) rotationally molded tube helps increase the volume of airflow by 35.7% CFM GAIN to your engine and provides an increase of 14.0 horsepower and 15.1 torque with no tune required. 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.
