Snow Performance Stage 2.5 Boost Cooler Water-Meth Injection Kit

2015–2020 Dodge Challenger / Charger SRT Hellcat & Redeye / Jeep Grand Cherokee Trackhawk 6.2L HEMI

Part #: SNO-2171-BRD

Overview

The Snow Performance Stage 2.5 Boost Cooler Water-Methanol Injection Kit is a precision-engineered system designed to enhance the performance and reliability of forced induction Dodge and Jeep vehicles equipped with 6.2L HEMI supercharged engines. Compatible with 2015–2020 Dodge Challenger SRT Hellcat, Challenger SRT Hellcat Redeye, Charger SRT Hellcat, and Jeep Grand Cherokee Trackhawk models, this kit improves engine efficiency by cooling intake air and raising effective fuel octane by up to 25 points.

Ideal for enthusiasts seeking consistent power gains and safer engine operation under high boost conditions, this water-methanol injection system reduces detonation risk, allowing for more aggressive tuning and improved throttle response without compromising engine longevity. The Stage 2.5 kit combines advanced technology with durable components for a reliable upgrade that integrates seamlessly with your vehicle.

Key Features

Snow Performance’s Stage 2.5 Boost Cooler kit incorporates cutting-edge technology and premium materials to deliver superior performance and ease of use:

• Progressive VC-50 controller with ISO 9001 certification for precise, proportional injection based on boost pressure
• Custom-engineered water-methanol injection throttle body spacer plate for optimal integration and injection efficiency
• Durable stainless steel braided line with 4AN fittings ensuring reliable fluid delivery and easy installation
• Adjustable start and full injection points to tailor injection curves to specific engine and tuning requirements
• Integrated 52mm gauge combining boost pressure readout and injection control in one compact unit
• 7-color OLED display (Blue, White, Red, Yellow, Orange, Purple, Green) customizable to match OEM gauges or personal preference
• Real-time monitoring of boost levels, injection percentage, low fluid warnings, secondary nozzle activation, prime function, and fault codes
• Designed to improve combustion cooling and increase octane rating for safer, more efficient power delivery

Construction & Design

Built for durability and performance, the Stage 2.5 Boost Cooler kit features a precision-machined throttle body spacer plate that ensures optimal injection placement for maximum cooling and combustion enhancement. The stainless steel braided lines resist abrasion and heat, providing long-lasting reliability in the demanding engine bay environment. The VC-50 controller’s robust housing and vibrant OLED display offer clear visibility and intuitive operation under all lighting conditions, making it easy to monitor and adjust injection parameters on the fly.

Performance & Sound

By injecting a carefully metered mixture of water and methanol into the intake system, this kit effectively cools the intake charge and raises the effective octane rating of pump fuel by up to 25 points. This reduces the risk of detonation, enabling more aggressive ignition timing and higher boost levels without compromising engine safety. Cooler intake temperatures also improve combustion efficiency and power output. While the system does not directly alter exhaust sound, the enhanced performance and engine protection allow drivers to confidently push their vehicles harder on the street or track.

Installation & Fitment

The Snow Performance Stage 2.5 Boost Cooler kit is designed for straightforward installation on compatible Dodge and Jeep forced induction models. It includes all necessary components such as a custom throttle body spacer and stainless steel braided lines with 4AN fittings for a clean, secure fit. The VC-50 controller mounts easily within the driver’s line of sight and integrates seamlessly with existing boost systems. Installation requires basic mechanical skills and common hand tools, with no major modifications needed to the vehicle’s intake or fuel systems.

Ideal For

This kit is perfect for performance enthusiasts and tuners who own forced induction Dodge Challengers, Chargers, or Jeep Grand Cherokee Trackhawks and want to safely increase power output while maintaining engine reliability. It is especially beneficial for those running pump gas who seek to raise octane levels without switching to race fuels. Whether you are a daily driver, weekend warrior, or track enthusiast, the Stage 2.5 Boost Cooler kit helps achieve cooler intake temperatures, reduced knock, and improved throttle response for a more confident driving experience.

Snow Performance specializes in water‑methanol injection systems designed to reduce intake air temps and support higher boost and timing safely. Popular on forced-induction street/strip builds as well as some tow and diesel applications, Snow kits help manage detonation risk and can enable more consistent power when intake temps and load get aggressive.
