Filter Options

The Momentum GT intake system offers two high-performance filter media options to suit different driving preferences and maintenance needs:

• Pro 5R Oiled Filter: Features five layers of progressively finer cotton gauze for maximum airflow and horsepower gains. This washable and reusable filter is ideal for enthusiasts seeking peak performance and track-ready filtration.
• Pro DRY S Non-Oiled Filter: Composed of three layers of synthetic media, this oil-free filter provides easy maintenance and is perfect for daily drivers or light off-road use where convenience is a priority.

Construction & Design

The Momentum GT Cold Air Intake is built with high-quality materials engineered to withstand harsh under-hood conditions. The intake housing is crafted from XLPE (cross-linked polyethylene), a durable polymer known for its excellent heat resistance and structural integrity. This one-piece sealed enclosure minimizes heat soak and protects the filter from contaminants while maintaining optimal airflow.

Stainless steel hardware and premium silicone couplings ensure long-lasting durability and a tight, leak-proof seal. The flexible bellows couplings accommodate engine movement, preventing stress on the intake components and maintaining consistent performance over time.

Performance & Sound

Dyno testing confirms substantial performance improvements with the Momentum GT Cold Air Intake. The Pro 5R filter option delivers up to +23 horsepower and +26 lb-ft of torque, while the Pro DRY S option provides gains of up to +18 horsepower and +21 lb-ft of torque. Both filters increase airflow significantly over the factory intake—23% for the Pro 5R and 18% for the Pro DRY S—resulting in improved throttle response and engine efficiency.

In addition to power gains, the intake enhances engine sound, providing a deeper and more aggressive intake note that complements the Ram 6.4L 392’s naturally aspirated V8 character.

Installation & Fitment

The aFe Momentum GT Cold Air Intake is designed for a direct bolt-on installation with no permanent modifications required. It utilizes existing factory air inlet points and auxiliary air inlets to optimize airflow without compromising fitment or vehicle aesthetics. Installation can typically be completed with basic hand tools and does not require specialized equipment, making it accessible for experienced DIYers and professional installers alike.

This intake system is specifically engineered to fit 2019 through 2025 Ram 2500 and 3500 models equipped with the 6.4L 392 engine, ensuring precise compatibility and seamless integration.

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.

• Each order Includes all 8 coilpacks

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.
