Snow Performance Stage 2 Boost Cooler Water-Methanol Injection Kit

2006–2023 Dodge Challenger / Charger 5.7L, 6.1L, 6.4L Forced Induction Engines

SNO-2171-BRD-T

Overview:

The Snow Performance Stage 2 Boost Cooler Water-Methanol Injection Kit is a precision-engineered solution designed specifically for forced induction Dodge Challenger and Charger models from 2006 through 2023 equipped with 5.7L, 6.1L, or 6.4L engines. This advanced system enhances engine performance by injecting a water-methanol mixture that effectively increases pump gas octane by up to 25 points, allowing for more aggressive tuning and increased power output while maintaining cooler combustion temperatures.

Ideal for supercharged or turbocharged Challengers and Chargers, this kit improves engine efficiency and durability by reducing detonation and heat-related stress. The system’s progressive injection strategy adapts to boost pressure, delivering precise amounts of water-methanol to optimize performance across a wide operating range without compromising drivability.

Key Features:

Snow Performance’s Stage 2 Boost Cooler kit combines innovative technology with robust components to ensure reliability and ease of installation. Key features include:

• Custom water-methanol injection throttle body spacer plate designed for direct fitment on Dodge Challenger and Charger models with forced induction.
• Progressive VC-50 controller with ISO 9001 manufacturing certification, providing proportional injection based on boost pressure for precise tuning.
• 7-color OLED display (Blue, White, Red, Yellow, Orange, Purple, Green) that functions as both a boost gauge and injection controller, allowing customization to match OEM gauge colors.
• Adjustable start and full injection points to tailor engagement and delivery curves according to engine requirements.
• Durable stainless steel braided line and 4AN fittings for superior reliability and leak resistance.
• Integrated low fluid level warning, secondary nozzle activation, prime button, and fault code display for enhanced system monitoring.
• Designed specifically for Dodge Challengers and Chargers with 5.7L, 6.1L, and 6.4L engines equipped with superchargers or turbochargers.
• Tank not included, allowing flexibility for custom reservoir solutions.

Construction & Design:

The Stage 2 Boost Cooler kit is built with high-quality materials to withstand the demanding conditions of forced induction performance applications. The throttle body spacer plate is precision-machined to ensure a perfect fit and optimal flow characteristics. Stainless steel braided lines paired with 4AN fittings provide exceptional durability and resistance to abrasion, heat, and pressure, ensuring long-lasting performance without leaks.

The VC-50 controller features a bright, multi-color OLED screen housed in a compact, rugged enclosure. Its intuitive interface allows for easy adjustments and real-time monitoring of boost and injection parameters, making it a versatile tool for both street and track use.

Performance & Sound

By injecting a water-methanol mixture proportional to boost pressure, this system effectively cools the intake charge and suppresses detonation, enabling higher boost levels and more aggressive timing without risk of knock. This results in increased horsepower and torque while maintaining engine reliability. The cooler combustion temperatures also contribute to improved engine longevity and consistent performance under demanding conditions. The system operates silently, maintaining the factory exhaust note and overall vehicle sound profile.

Installation & Fitment:

The Snow Performance Stage 2 Boost Cooler kit is designed for straightforward installation on 2006–2023 Dodge Challenger and Charger models equipped with 5.7L, 6.1L, or 6.4L forced induction engines. The kit includes all necessary hardware for mounting the throttle body spacer and routing the injection lines. The VC-50 controller can be mounted conveniently within the driver’s reach for easy monitoring and adjustments.

While the kit does not include a reservoir tank, it is compatible with a variety of aftermarket or custom tanks, allowing installers to tailor the system to their specific setup. Basic mechanical skills and common hand tools are sufficient for installation, with no major modifications required.

What's Included:

• Custom water-methanol injection throttle body spacer plate
• VC-50 progressive boost controller with 7-color OLED display
• Stainless steel braided injection line
• 4AN fittings for secure, leak-free connections
• Wiring harness and mounting hardware
• Installation instructions

Ideal For:

This kit is perfect for Dodge Challenger and Charger enthusiasts seeking to maximize the performance of their supercharged or turbocharged 5.7L, 6.1L, or 6.4L engines. Whether used for street performance, drag racing, or track applications, the Stage 2 Boost Cooler offers a reliable and effective method to increase power safely while protecting the engine from heat and detonation. It is especially suited for tuners and builders who want precise control over water-methanol injection with a high-quality, OEM-style interface.

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.
