Its innovative design ensures easy installation and maintenance, making it a practical choice for both street and light-duty applications.

Key Features

The Momentum HD Cold Air Intake is packed with advanced features that set it apart from the competition:

• Large 9" tall, 360-degree radial flow air filter with a 5-1/2" flange for maximum airflow
• Pro DRY S oil-free synthetic media with three progressive layers for superior filtration and dust holding capacity
• Inverted top design increases filter surface area for extended service intervals
• One-piece sealed housing made from heat-resistant cross-linked polyethylene (XLPE) with patented filter-to-housing interface
• Clear sight window for quick and easy filter inspection without disassembly
• Dyno-tuned intake tube crafted from durable, heat-soak resistant XLPE material
• Stainless steel T-bolt clamps and premium bellows silicone coupling for secure, flexible connections
• Optional auxiliary air inlet with plug included for additional airflow customization
• Designed with fewer parts to simplify installation and reduce potential leak points

Construction & Design

The Momentum HD intake system is built with durability and performance in mind. The housing is constructed from heat-resistant cross-linked polyethylene (XLPE), which withstands engine bay heat and resists cracking or warping. Its patented filter-to-housing interface ensures a tight, sealed fit that minimizes air leaks and maximizes efficiency.

The large Pro DRY S filter uses a three-layer synthetic media that does not require oiling, making maintenance quick and mess-free. Reinforced metal mesh supports the filter structure to prevent collapse under high airflow conditions. The intake tube’s smooth, computer-designed shape is optimized for airflow dynamics, contributing to improved engine breathing and power delivery.

Performance & Sound

This intake system is dyno-tuned to optimize airflow and enhance engine performance without compromising reliability. The increased volume and efficiency of the air filter combined with the precision-engineered intake tube help improve throttle response and can contribute to modest power gains. The design also helps produce a subtle, aggressive intake sound that enhances the driving experience without being intrusive.

Installation & Fitment

The aFe Momentum HD Cold Air Intake is designed for a straightforward, bolt-on installation on 2019 through 2023 RAM 2500 and 3500 models with the 6.7L Cummins engine. The one-piece housing connects directly to the factory air inlet scoop without requiring additional hardware, and the system includes all necessary clamps and couplings. Installation typically requires basic hand tools and can be completed in under an hour with no permanent modifications to the vehicle.
