Snow Performance Stage 3 Boost Cooler Water Injection Kit

1994–2009 Dodge Ram 2500 / 1994–2007 Dodge Ram 3500 5.9L Cummins

SNO-500-BRD

Overview:

The Snow Performance Stage 3 Boost Cooler Water Injection Kit is engineered specifically for Dodge Ram 2500 (1994–2009) and Ram 3500 (1994–2007) models equipped with the 5.9L Cummins diesel engine. This advanced water-methanol injection system is designed to significantly reduce exhaust gas temperatures (EGTs), improve air intake cooling, and enhance overall engine performance during heavy towing and demanding driving conditions.

Ideal for diesel enthusiasts who prioritize engine longevity and reliability, this kit delivers up to a 300°F reduction in EGTs, cleaner engine components, and improved fuel economy. The integrated 2D mapped controller intelligently manages injection based on boost pressure and EGT readings, ensuring optimal cooling and power gains without the need for invasive installation or additional gauge pods.

Key Features:

The Stage 3 Boost Cooler combines cutting-edge technology with durable components to provide a comprehensive solution for high-performance diesel applications:

• 2D mapped controller that adjusts injection based on boost pressure and exhaust gas temperatures
• Reduces EGTs by 100–300°F to protect engine components and improve efficiency
• Integrated boost gauge, water-methanol controller, and EGT monitor in a single unit
• Non-invasive installation with mounting options on the steering column or dash—no drilling required
• Includes a large 7-gallon tank for extended operation and trip readiness
• Stainless steel braided lines with 4AN fittings for superior durability and leak resistance
• Dual nozzle upgrade and high-flow solenoids for enhanced injection capacity
• Snow Performance Hypersonic water-methanol nozzles and high-flow check valve for reliable performance
• 300 PSI sealed UHO pump designed for extreme environments

Construction & Design:

Built with quality and longevity in mind, the Stage 3 Boost Cooler kit features stainless steel braided lines and 4AN fittings that resist corrosion and withstand high pressure. The sealed 300 PSI UHO pump is engineered for extreme environmental conditions, ensuring consistent and reliable fluid delivery. The controller’s compact design allows for easy mounting without altering the vehicle’s interior, preserving factory aesthetics while providing comprehensive monitoring and control.

Performance & Sound

This water-methanol injection system enhances engine performance by cooling the intake air charge and reducing EGTs, which allows the engine to safely produce more power under load. Users can expect an increase of 65+ horsepower, making heavy towing and hill climbs easier and less stressful on the engine. Additionally, the system contributes to cleaner combustion, resulting in reduced emissions and improved fuel economy.

Installation & Fitment:

The Snow Performance Stage 3 Boost Cooler kit is designed for straightforward installation on Dodge Ram 2500 models from 1994 to 2009 and Ram 3500 models from 1994 to 2007 with the 5.9L Cummins engine. The non-invasive controller mounts easily on the steering column or dash without the need for drilling or additional gauge pods. All necessary hardware, fittings, and hoses are included for a complete, trip-ready setup.

What's Included:

• 300 PSI Extreme Environment Sealed UHO Pump
• 7-Gallon Tank Upgrade

Emissions Note

For customers requiring CARB Executive Order compliance for use in all 50 states, Snow Performance offers a legal system under part number SNO-50100. Please verify local regulations before purchase.

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.
