• VC-50 progressive controller with ISO 9001 certification for precise, proportional injection based on boost pressure
• 7-color OLED display providing real-time data including boost levels, injection percentage, low fluid warnings, secondary nozzle activation, and fault codes
• Adjustable start and full injection points to tailor injection curves to your engine’s specific boost profile
• Stainless steel braided lines and high-quality 4AN fittings for superior durability and leak resistance
• Integrated boost gauge functionality within the VC-50 controller for convenient monitoring
• Designed for forced induction Dodge Challengers and Chargers with no included fluid tank, allowing custom tank selection and installation flexibility
• Improves octane rating by up to 25 points, reducing knock and enabling safer, more aggressive tuning

Construction & Design

Snow Performance’s Stage 2.5 Boost Cooler kit is built with premium materials to withstand the demanding environment of high-performance forced induction engines. The throttle body spacer plate is precision-machined to ensure a perfect seal and optimal flow characteristics, maintaining engine efficiency and reliability.

Durable stainless steel braided lines provide superior abrasion resistance and longevity compared to standard rubber hoses, while 4AN fittings ensure secure, leak-free connections. The VC-50 controller features a robust housing and a high-resolution OLED screen for clear, customizable readouts and dependable operation under all conditions. Manufactured under strict ISO 9001 standards, this controller guarantees consistent quality and long-term durability.

Installation & Fitment

This water-methanol injection kit is engineered for direct fitment on Dodge Charger models from 2008 through 2021 and Dodge Challenger models from 2009 through 2021, covering the 5.7L HEMI, 6.1L SRT8, and 6.4L 392 engines equipped with forced induction. Installation is straightforward, requiring no major modifications thanks to the custom throttle body spacer plate and pre-assembled stainless braided lines.

The kit includes all necessary mounting hardware and detailed instructions to facilitate a clean, professional installation. Note that the Stage 2.5 kit does not include a fluid tank, giving users the flexibility to select a tank size and mounting location that best suits their vehicle setup and usage preferences.

Ideal For

This kit is perfect for Dodge Charger and Challenger owners who have upgraded to forced induction or are planning to do so, and want to maximize the performance and safety of their 5.7L, 6.1L, or 6.4L supercharged or turbocharged engines. It is especially beneficial for enthusiasts aiming to increase octane rating, reduce intake air temperatures, and improve overall engine efficiency and power output while maintaining reliability under boost conditions.

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.
