Construction & Design

The Momentum GT intake system is constructed from high-quality, heat-resistant cross-linked polyethylene (XLPE), providing exceptional durability and resistance to heat soak under demanding conditions. The one-piece sealed housing protects the air filter and helps maintain lower intake air temperatures, which is critical for consistent engine performance and power delivery.

The innovative filter-to-housing interface reduces the number of components required, simplifying installation and enhancing system reliability. The oversized Pro 5R air filter features an inverted top design that increases surface area, extending service intervals and improving airflow efficiency. The intake tube is precision-engineered and dyno-tested to optimize airflow dynamics, contributing to improved throttle response and overall engine efficiency.

Performance & Sound

By delivering a larger volume of cooler, denser air to the engine, the Momentum GT Cold Air Intake System improves combustion efficiency, resulting in noticeable gains in horsepower and torque throughout the powerband. The system’s design effectively reduces intake air temperatures, helping maintain consistent performance even during spirited driving or track sessions.

Additionally, the intake produces a more aggressive induction sound that enhances the driving experience without excessive drone, striking a balance between performance and refinement that appeals to enthusiasts seeking both power and auditory engagement.

Installation & Fitment

The Momentum GT Cold Air Intake System is designed for a straightforward, bolt-on installation requiring minimal tools and no permanent modifications. Its innovative filter-to-housing interface and reduced hardware count allow for quick assembly, typically completed within an hour. Factory components and warranty considerations remain intact.

For 2015 and newer Dodge Challenger models, the auxiliary air inlet can be connected to the headlight air inlet using the optional Dynamic Air Scoop (sold separately) to further enhance airflow. If not utilized, the inlet is sealed with the included plug to maintain system integrity.

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
• Direct bolt-on installation, plug and play

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.
