aFe Momentum HD Cold Air Intake System
2007–2009 Dodge Ram 2500 / Ram 3500 5.7L / 6.7L Cummins
Part #: 51-72003
Overview
The aFe Momentum HD Cold Air Intake System is a precision-engineered performance upgrade designed specifically for 2007 to 2009 Dodge Ram 2500 and Ram 3500 trucks equipped with 5.7L gas or 6.7L Cummins diesel engines. This system replaces the factory airbox and filter with a custom roto-molded housing and a high-flow Pro DRY S air filter, delivering cooler, denser air to the engine for improved combustion efficiency.
Ideal for truck owners seeking a reliable and straightforward performance enhancement, the Momentum HD intake system boosts horsepower, torque, and throttle response while maintaining excellent filtration to protect your engine. It offers a balanced upgrade that enhances power and fuel economy without compromising engine safety or requiring complex modifications.
Key Features
Engineered for durability and performance, the Momentum HD Cold Air Intake System includes:
- Custom CAD-designed roto-molded housing made from heat-resistant black cross-linked polyethylene for superior thermal insulation and long-lasting durability
- Large clear sight window for quick and easy filter inspection without removing the airbox
- High-quality billet aluminum crankcase fitting for secure and straightforward installation
- CAD-engineered air scoop that efficiently directs cool ambient air to the performance air filter
- Sealed intake design featuring a radial flow Pro DRY S air filter with three oil-free synthetic media layers for excellent airflow and 99.2% filtration efficiency
- Premium stainless steel clamps and silicone couplings for secure, vibration-resistant connections
- One-piece airbox and heat shield that seals tightly against the hood liner to isolate the filter from engine heat
- 3-angle velocity stack to smooth airflow transition and maximize power gains
- Designed for quick, bolt-on installation with no cutting, drilling, or modifications required
Construction & Design
The Momentum HD intake system features a roto-molded housing crafted from black cross-linked polyethylene, a heat-resistant plastic that helps maintain cooler intake air temperatures for optimal engine performance. The one-piece airbox and heat shield are constructed from rugged 16-gauge powder-coated steel, providing durability and effective thermal isolation from engine heat.
Additional design elements include a large clear inspection window for easy maintenance checks and a billet aluminum crankcase fitting that enhances installation and functionality. Premium stainless steel hardware and silicone couplings ensure a secure, long-lasting fit that withstands vibration and harsh operating environments.
Performance & Sound
By increasing the volume of cooler, denser air entering the engine, the aFe Momentum HD Cold Air Intake System improves combustion efficiency, resulting in noticeable gains in horsepower and torque. The radial flow Pro DRY S filter media allows approximately twice the airflow of a stock air filter while maintaining a 99.2% filtration efficiency rating, protecting your engine from harmful contaminants.
This intake system also enhances throttle response and can contribute to improved fuel economy. Additionally, it produces a subtle yet aggressive induction sound that enhances the driving experience without excessive noise, providing a refined performance tone.
Installation & Fitment
The Momentum HD Cold Air Intake System is designed for a direct bolt-on installation that replaces the factory airbox and filter with no cutting, drilling, or modifications required. The kit includes all necessary hardware and detailed instructions, allowing installation in an hour or less using basic hand tools.
The sealed airbox design fits perfectly under the hood and seals tightly against the hood liner to keep hot engine air away from the intake. This system is engineered specifically to fit 2007 to 2009 Dodge Ram 2500 and Ram 3500 trucks with 5.7L gas or 6.7L Cummins diesel engines, ensuring a precise and secure fit.

What does the Available to Promise date mean?
ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
