Filter Options

This intake system is available with two high-performance filter options to suit different driving conditions and preferences:

• Pro DRY S: An oil-free, 3-layer synthetic media filter designed for dry or dusty environments. It offers excellent filtration, easy maintenance, and convenience without the need for oiling.
• Pro 5R: A pre-oiled, 5-layer cotton gauze filter engineered for maximum airflow and performance. Ideal for aggressive driving and horsepower demands, it provides superior filtration and reusable design.

Construction & Design

The Momentum GT intake features a one-piece, roto-molded housing made from heat-resistant black cross-linked polyethylene, ensuring durability and resistance to heat soak. This design minimizes component count and seals tightly to maintain the coldest possible air charge. The intake tube is also roto-molded from durable plastic and includes a built-in resonance chamber to optimize airflow dynamics and enhance intake sound quality.

Attention to detail is evident with the inclusion of a billet aluminum crankcase fitting and an injection-molded temperature sensor mount, both pre-installed to simplify the installation process and ensure a precise fit.

Performance & Sound

The aFe Momentum GT Cold Air Intake significantly improves engine breathing by increasing airflow up to 24% over the factory system. This results in measurable horsepower and torque gains, enhancing acceleration and overall engine responsiveness. The integrated resonance chamber in the intake tube also refines the induction sound, providing a deeper, more aggressive intake note without excessive drone.

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.
