Snow Performance Stage 3 Boost Cooler Water Injection Kit

2007–2020 Dodge Ram 2500 / Ram 3500 6.7L Cummins Diesel

SNO-510-BRD

Overview:

The Snow Performance Stage 3 Boost Cooler Water Injection Kit is engineered specifically for Dodge Ram 2500 and 3500 trucks equipped with the 6.7L Cummins diesel engine from 2007 through 2020. Designed for diesel enthusiasts who demand enhanced engine protection and performance during heavy towing, this advanced water-methanol injection system significantly reduces exhaust gas temperatures (EGTs) and intake air temperatures. By injecting a precise mixture based on boost pressure and EGT readings, it helps maintain optimal combustion conditions, resulting in cleaner engine components, lower emissions, and improved fuel economy.

This kit is ideal for owners who regularly tow heavy loads or drive in demanding conditions where high EGTs can threaten engine longevity. The Stage 3 Boost Cooler delivers up to a 300°F reduction in EGTs and can provide an estimated 65+ horsepower gain, making hill climbs and heavy towing easier and safer. Its non-invasive installation and integrated controller make it a practical upgrade without compromising vehicle warranty.

Key Features:

The Snow Performance Stage 3 Boost Cooler combines cutting-edge technology with durable components to optimize diesel engine performance and protection. Key features include:

• 2D mapped controller that adjusts injection based on boost pressure and EGT for precise cooling and performance
• Significant reduction in exhaust gas temperatures by 100–300°F, protecting engine components from heat damage
• Integrated boost gauge, water-methanol controller, and EGT monitor in a single unit for streamlined dashboard installation
• Non-invasive mounting options on steering column or dash, requiring no drilling or additional gauge pods
• Stainless steel braided lines with 4AN fittings for durability and leak resistance
• 7-gallon tank included for extended range and trip-ready installation
• Dual nozzle and high flow solenoid upgrades for enhanced injection capacity
• Hypersonic water-methanol nozzles and high flow check valve for consistent atomization and flow control
• Maintains vehicle warranty by leaving no permanent signature on the truck

Construction & Design:

Built with premium materials, the Stage 3 Boost Cooler kit features stainless steel braided lines and high-quality 4AN fittings to withstand extreme environments and high pressures. The sealed 300 PSI UHO pump ensures reliable fluid delivery under demanding conditions. The controller is designed for easy integration into the vehicle’s interior without permanent modifications, preserving the truck’s factory appearance and warranty. The included EGT probe assembly and boost line hardware are engineered for precise sensor placement and accurate data collection, enabling the controller to optimize injection timing and volume effectively.

Performance & Sound

By injecting a water-methanol mixture based on real-time boost and EGT data, this system lowers intake air temperatures and exhaust gas temperatures, which improves combustion efficiency and reduces engine stress. The result is a noticeable increase in horsepower—up to 65+ HP—especially beneficial when towing heavy loads or climbing steep grades. Additionally, the cooler combustion temperatures contribute to cleaner engine internals and reduced emissions, promoting longer engine life and better fuel economy. The system operates quietly and seamlessly, without altering the truck’s exhaust sound.

Installation & Fitment:

The Snow Performance Stage 3 Boost Cooler kit is designed for straightforward installation on Dodge Ram 2500 and 3500 models from 2007 to 2020 with the 6.7L Cummins engine. The controller mounts easily on the steering column or dash, eliminating the need for drilling or additional gauge pods. The kit includes all necessary hardware, fittings, and lines for a complete installation. The 7-gallon tank allows for extended operation without frequent refills, making it suitable for long trips and heavy-duty use. Professional installation is recommended to ensure optimal sensor placement and system calibration.

What's Included:

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

Emissions Note

For customers requiring CARB compliance, Snow Performance offers a 50-state legal version of this system under part number SNO-50100, which carries the CARB Executive Order #D-723. This ensures legal operation in all states, including California.

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.
