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.

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
- Highest quality internal components and finish
- MOPAR Orange, Purple, Green or Steel Gray high temperature heat resistant outer housing
- Heat resistant silicone boot
- Compatible with Naturally Aspirated and Forced Induction engines
- Improved Throttle Response
- Improved POWER
- Improved MPG
- No Tuning Required!!
- Heavy duty primary copper core winding.
- Higher quality Iron core with stronger laminations.
- Increased amount of secondary core windings.
- Precision Spool to promote Orthocycling winding and mitigate wild winding.
- Sustained power delivery even at high RPM operation
- High Density Polymer Housing.
- Heavy Duty, high-temperature, epoxy filled housing resists shock and vibration. Our dielectric compound completely penetrates coil windings assuring perfect insulation even upon exposure to high voltage conditions. Engineered to resist humidity, wear, vibration, impact and chemicals such as gasoline, oils and brake fluids. Will not degrade or crack even under severe thermal cycling.

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.
E3 Spark Plugs
11-24 Chrysler 300 / Dodge Challenger / Charger 6.4L 392
E3.74
The E3.74 Automotive Spark Plug is a high-performance replacement plug designed for vehicle. Engineered with E3’s patented DiamondFIRE technology, the plug promotes a faster, more complete combustion cycle—boosting horsepower, increasing fuel efficiency, and reducing emissions over the long term. This spark plug features a 14mm thread diameter, 1.000" reach, and taper seat to ensure a precise fit for your vehicle engine. Its triple-legged ground electrode secures the DiamondFIRE tip, enhancing heat dissipation and generating greater turbulence in the combustion chamber for maximum efficiency.
