Construction & Design

The intake system features a rotomolded plastic intake tube crafted with smooth contours and gentle bends to minimize airflow turbulence and maximize efficiency. The one-piece aluminum heat shield is powder-coated for long-lasting durability and engineered to seal tightly against the hood, effectively isolating the air filter from engine heat to ensure intake of cooler air. The Pro DRY S air filter utilizes three layers of randomly porous synthetic fabric, balancing high airflow with superior filtration without the need for oiling. All sealing surfaces and structural components are made from 100% polyurethane, providing resilience under high temperatures and extended service life.

Performance & Sound

Replacing the factory intake with the Magnum FORCE Stage-2 system allows your 6.7L Cummins engine to breathe more freely, resulting in improved combustion efficiency and increased power output. This enhanced airflow delivers sharper throttle response and can contribute to better fuel economy under certain driving conditions. Additionally, the open-element design combined with the smooth intake tube produces a more aggressive engine induction sound, enhancing the driving experience without excessive noise.
