S&B Cold Air Intake | Ram Cummins 6.7L | 2013-2018

The S&B Cold Air Intake for the 2013-2018 Ram 6.7 Cummins delivers a 54.6% airflow increase over stock with a 99.55% efficiency rating, and it's the S&B Cummins intake with a built-in Ram Air Swing Gate that opens at wide-open throttle for maximum air volume when your engine demands it most.

It replaces the OEM airbox with a high-flow sealed system. The standout feature is the Ram Air Swing Gate: at normal driving the enclosed box delivers filtered, heat-shielded air, and the moment you plant the pedal, the gate opens automatically and channels additional airflow. You get filtered air at cruise and maximum volume at peak demand, all at a 99.55% efficiency rating.

The stock Mass Airflow (MAF) sensor location is retained, so your ECM reads a normal signal with no check engine light and no tuning required. You can run oiled or dry filter media with multiple airflow configurations, and install is bolt-on with all hardware included. Fits 2013 through 2018 Ram 2500 and Ram 3500 with the 6.7L Cummins across all pickup trims, cab styles, and box lengths; does not fit Cab & Chassis trucks.
