• Premium stainless-steel clamps and flexible silicone coupler for secure installation and vibration resistance

Construction & Design

The intake system is crafted from high-quality, heat-resistant XLPE material that withstands the harsh under-hood environment while maintaining structural integrity. The precision-molded tubing is designed to minimize turbulence and maximize airflow efficiency, ensuring the turbocharger receives a steady supply of cool, dense air. The sealed airbox features an innovative filter-to-housing interface that guarantees a tight, secure fit to prevent unfiltered air from entering the engine.

The Pro 10R air filter is constructed with ten layers of premium cotton gauze treated with oil to trap even the finest dust and debris without sacrificing airflow. This combination of materials and design results in a robust, reliable intake system built to enhance engine performance and longevity.

Performance & Sound

The Momentum HD Cold Air Intake is dyno-tuned to optimize airflow dynamics, resulting in noticeable gains in horsepower and torque. By delivering a higher volume of cooler air directly to the turbocharger, the system improves combustion efficiency and throttle response. Additionally, the intake produces a subtle, aggressive induction sound that enhances the driving experience without being intrusive.

Installation & Fitment

Installation is straightforward and designed to fit the 2025–2026 RAM 2500 and 3500 models with the 6.7L Cummins engine. The kit includes all necessary hardware, clamps, and couplers for a secure, bolt-on fitment. No major modifications or cutting are required, allowing for a clean installation that maintains factory reliability and warranty considerations. Routine maintenance is simplified by the clear sight window and washable filter media.
