JLT Cold Air Intake System

2005–2024 Chrysler 300, Dodge Challenger, Dodge Charger, Dodge Magnum 5.7L Hemi & 6.1L SRT8

Part #: CAI-DH05

Overview

The JLT Cold Air Intake System is a high-performance upgrade designed specifically for Chrysler 300, Dodge Challenger, Dodge Charger, and Dodge Magnum models equipped with the 5.7L Hemi and 6.1L SRT8 engines from 2005 through 2024. This intake system is engineered to optimize airflow by reducing restrictions found in the factory air intake, delivering noticeable gains in horsepower and throttle response. Ideal for enthusiasts seeking improved engine efficiency and enhanced driving dynamics, the JLT Cold Air Intake provides a straightforward bolt-on solution that elevates your vehicle’s performance without compromising reliability.

By drawing cooler, denser air from outside the engine bay, this system helps maximize combustion efficiency, resulting in increased power output and a more aggressive engine sound. Whether you’re upgrading for street performance or spirited driving, the JLT Cold Air Intake is a proven way to unlock additional horsepower and improve overall engine breathing.

Key Features

Designed with precision and performance in mind, the JLT Cold Air Intake offers a range of features that set it apart from stock systems:

• Engineered to reduce air restriction and improve airflow over factory intakes
• Provides an average gain of 10-20 rear-wheel horsepower (RWHP)
• Massive, highly efficient air filter for superior filtration and airflow
• Large rotomolded plastic intake tube with a smooth, black textured finish
• No restrictive choke points or accordion-style bends found in OEM designs
• Fully rotomolded heat shield to minimize intake air temperatures
• Durable construction designed to withstand heat and harsh underhood conditions
• Direct bolt-on installation with no permanent modifications required

Construction & Design

The JLT Cold Air Intake features a robust rotomolded plastic intake tube engineered for maximum airflow efficiency. This material choice ensures a smooth internal surface that minimizes turbulence and pressure drop, unlike the restrictive accordion-style tubing commonly used in factory intakes. The intake tube’s large diameter allows for a higher volume of air to reach the engine, supporting improved combustion and power gains.

Complementing the intake tube is a fully rotomolded heat shield designed to isolate the intake air from engine heat. By maintaining cooler air temperatures, the system enhances volumetric efficiency and helps sustain consistent performance even under demanding driving conditions. The included air filter is oversized and constructed from high-quality materials to provide excellent filtration while allowing unrestricted airflow.

Performance & Sound

The JLT Cold Air Intake delivers a measurable increase in horsepower, with gains typically ranging from 10 to 20 RWHP depending on the specific vehicle and engine configuration. This improvement is achieved by optimizing the air intake path to reduce restrictions and deliver cooler, denser air to the combustion chambers. In addition to power gains, the intake enhances engine sound, providing a deeper and more aggressive induction tone that complements the naturally aspirated Hemi and SRT8 engines.

Installation & Fitment

Installation of the JLT Cold Air Intake is straightforward and designed to fit the specified Chrysler and Dodge models without the need for cutting, drilling, or permanent modifications. The kit includes all necessary hardware and detailed instructions to facilitate a smooth, bolt-on installation process. Fitment covers a broad range of vehicles, including:

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.
