Give Your New Cummins The Airflow It Was Built For

The redesigned 6.7L Cummins in your 2025-2026 Ram 2500 or 3500 demands real airflow to reach its full potential, and aFe Power built the Momentum HD specifically to deliver it. This sealed intake system eliminates the hidden restrictions found in the factory setup, replacing them with precision-molded tubing that routes smooth, efficient airflow straight to the turbocharger. According to aFe, this translates to up to 13 additional horsepower and 35 additional lb-ft of torque, along with a 9% increase in airflow over stock, all without requiring any ECU tuning to install. The sealed housing design blocks engine bay heat, dirt, and contaminants from reaching the filter, delivering cooler, denser air for more consistent performance. A clear sight window lets you check filter condition at a glance, so routine maintenance doesn't mean tearing the whole system apart just to see if it's time for a cleaning. The Pro DRY S filter captures dirt without oil, using three layers of dense synthetic fibers to trap particles, which makes cleaning and maintaining the filter especially convenient for owners who'd rather skip the re-oiling step. For a new-generation Cummins that's ready for more, this intake gives it room to breathe without the mess.

Sealed Housing Construction Engineered Around Real-World Testing

The aFe Power 50-70137D Momentum HD Cold Air Intake is engineered specifically for 2025-2026 Ram 2500 and 3500 trucks equipped with the 6.7L Cummins engine. The rotomolded housing and intake tube are built for exceptional strength and rigidity, while a clear sight window allows filter inspection without disassembly. The intake tube itself is dyno-tuned and constructed from heat-resistant, durable XLPE material, engineered based on real-world testing to optimize airflow and maximize power and torque. According to aFe, the system delivers a 9% airflow gain with a rated flow rate of 445 cubic feet per minute. The included Pro DRY S filter uses non-woven synthetic filter material in a closed air box design, paired with a custom-molded silicone coupler and premium stainless steel clamps for a secure, durable seal. A heat shield and all necessary mounting hardware are included, and no ECU tuning is required for installation.
