• Reduces intake noise while improving engine sound for a more aggressive tone

Construction & Design

The intake system features a robust 16-gauge steel heat shield finished with a durable powder coat to resist corrosion and heat soak. This shield effectively isolates the intake air from engine bay heat, ensuring cooler, denser air reaches the engine for improved combustion efficiency.

The intake tube is crafted from molded plastic, precisely shaped to optimize airflow dynamics and minimize turbulence. This design enhances volumetric efficiency, contributing to better throttle response and power delivery. The Pro 5R filter uses multiple layers of oiled cotton gauze media, providing excellent filtration without restricting airflow.

Performance & Sound

By increasing the volume and velocity of cold air entering the engine, the Magnum FORCE Stage-2 intake system helps unlock additional horsepower and torque potential inherent in the 6.1L HEMI engine. The system also reduces intake restriction, allowing the engine to breathe more freely under acceleration.

Additionally, the intake produces a more aggressive induction sound, enhancing the driving experience without excessive noise or drone. The powder-coated cover helps to quiet intake noise while maintaining airflow efficiency.

Installation & Fitment

Installation is straightforward and designed to be completed with basic hand tools. The one-piece heat shield fits precisely into the factory location without the need for cutting, drilling, or modifications. The intake tube and filter install easily with supplied hardware, making this a direct bolt-on upgrade for the 2006–2010 Jeep Grand Cherokee SRT8 6.1L HEMI.

This system is engineered to maintain factory fitment and clearance, ensuring compatibility with stock components and accessories.

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.
