Key Features

The Momentum HD Cold Air Intake system offers a range of innovative features designed to optimize airflow and engine protection:

• Precision-molded intake tubing crafted to eliminate airflow restrictions and deliver smooth air directly to the turbocharger
• Pro DRY S Air Filter featuring three layers of dense synthetic fibers that trap dirt effectively without the need for oiling
• Clear sight window integrated into the airbox for quick visual inspection of filter condition without disassembly
• Sealed airbox with an innovative filter-to-housing interface ensuring a secure, airtight fit
• Dyno-tuned intake tube engineered based on real-world testing to maximize power and torque output
• Durable XLPE heat-resistant material construction for long-lasting performance under extreme conditions
• Premium stainless-steel clamps included for secure installation and corrosion resistance
• Flexible silicone coupler allowing for precise fitment and vibration absorption

Construction & Design

The Momentum HD intake system is built with high-quality materials engineered to withstand the rigors of heavy-duty diesel use. The intake tube is constructed from heat-resistant XLPE (cross-linked polyethylene), which offers excellent durability and thermal stability to maintain consistent airflow temperatures. The sealed airbox design prevents unfiltered air from entering the engine bay, enhancing engine protection and performance reliability.

Attention to detail is evident in the precision molding of the intake components, ensuring a perfect fit and smooth airflow path. Stainless-steel clamps provide strength and corrosion resistance, while the silicone coupler offers flexibility to accommodate engine movement and vibrations without compromising the seal.

Performance & Sound

The aFe Momentum HD Cold Air Intake is dyno-tuned to optimize airflow for the 6.7L Cummins engine, resulting in improved horsepower and torque across the RPM range. By reducing intake restrictions and delivering cooler, denser air to the turbocharger, this intake system enhances throttle response and overall engine efficiency. Additionally, the design helps maintain a refined intake sound, providing a subtle performance tone without excessive noise.

Installation & Fitment

Installation of the Momentum HD Cold Air Intake is straightforward and designed to fit the 2025–2026 RAM 2500 and 3500 models with the 6.7L Cummins engine. The system uses factory mounting points and includes all necessary hardware for a secure, bolt-on fit. No major modifications or cutting are required, making it suitable for both professional installers and experienced DIY enthusiasts. The clear sight window simplifies routine maintenance by allowing quick filter inspections without removal.
