Construction & Design

The Momentum HD intake system features a rugged roto-molded housing constructed from black cross-linked polyethylene, chosen for its excellent heat resistance and durability. This single-piece housing design minimizes air leaks and heat soak by eliminating multiple components and joints. The intake tube is precision CAD-designed and roto-molded from high-quality plastic, ensuring a smooth airflow path that has been dyno-tuned for optimal performance.

Additional components include a billet aluminum crankcase fitting and a specially designed air scoop that efficiently directs cool ambient air to the filter. The housing’s large clear sight window allows for quick visual filter checks without disassembly, enhancing convenience. Premium stainless steel clamps and silicone couplings provide a secure, long-lasting seal capable of withstanding engine bay temperatures and vibrations.

Performance & Sound

The aFe Momentum HD Cold Air Intake System improves engine breathing by delivering cooler, denser air to the combustion chamber. This results in noticeable gains in horsepower and torque, along with improved throttle response. The radial flow Pro DRY S performance air filter, featuring three oil-free synthetic layers, offers approximately twice the airflow of a stock filter while maintaining excellent filtration efficiency of 99.2%.

While primarily designed for performance and efficiency, this intake system also enhances engine sound with a more aggressive tone during acceleration, enriching the driving experience without excessive noise.

Installation & Fitment

Installation is straightforward and can typically be completed in under an hour using basic hand tools. The system is designed to replace the factory air filter and airbox without any cutting, drilling, or modifications. It installs easily in place of the stock components, using supplied stainless steel hardware for secure mounting.

The one-piece housing seals against the hood with flexible rubber trim to isolate the filter from engine heat, ensuring consistent intake of cool air. This intake system is specifically engineered to fit 2010 to 2012 Dodge Ram 2500 and Ram 3500 trucks with 5.7L and 6.7L Cummins engines, guaranteeing a precise fit and seamless integration with factory components.

Ripp HEMI High Performance Coil Packs

05-25 5.7L, 6.1L, 6.2L, & 6.4L  HEMI Engines

MV8-CPK (8 Coilpacks)

Our coil pack is engineered from the ground up with higher quality materials, and increased amount of windings (turn ratio) in the primary and secondary winding. This provides a boost in millijoule power output, and this results in an increase in spark energy. With a stronger spark, cylinder flame speed is increased and thus adding up to an additional 20hp on the 5.7L and 25-30whp on the 6.4L. With this increased power output, you can expect a more responsive throttle input and a better driving experience overall. (For more technical information please see the tech notes below.)

Don't forget a fresh set of spark plugs. We recommend NGK Spark Plugs.

TECH NOTES

RIPP Technical information about cylinder flame speed and how an upgraded ignition system will directly effect power. 

An Internal combustion engine's "flame speed" refers to the rate at which the air-fuel mixture burns during the combustion process. This speed significantly impacts engine performance and efficiency. The faster flame speed will increase cylinder pressure. When a spark is hotter, it ignites the air-fuel mixture more rapidly, leading to faster combustion, and an increase in pressure. Higher cylinder pressure = more torque pushing down on the piston.

Flame front propagation speed: As the flame front propagates faster across the combustion chamber, the fuel burns more efficiently, releasing more energy. This, in turn, enhances the engine's power and responsiveness. Additionally, with a faster flame speed, the combustion process is completed sooner, reducing the chance of incomplete burn or unburned hydrocarbons being released into the exhaust gases. In summary, optimizing the flame speed by utilizing more spark energy can significantly improve engine performance. It enables the engine to operate more efficiently, delivering increased power output, improved fuel economy.

Spark Energy is measured in Millijoules (mj). A Factory coilpack will generate 35.8mj. This mj value is considered low for the cylinder displacement value, piston surface area and air/fuel mixture. A RIPP coilpack will generate 53.6mj. This 17.8mj increase over stock will dramatically increase pressure per square inch across the piston surface. At first start up you'll immediately notice a smoother operating engine, and a "calmer" exhaust tone. This is due to less waste or unburnt hydrocarbons and fuel. Engine response and engine horse power will increase throughout the RPM range.
