Snow Performance Stage 3 Boost Cooler Water Injection Kit

2007–2017 Dodge Ram 2500/3500 5.9L & 6.7L Diesel

Part #: SNO-510-T

Overview

The Snow Performance Stage 3 Boost Cooler Water Injection Kit is engineered specifically for Dodge Ram 2500 and 3500 models equipped with 5.9L and 6.7L diesel engines from 2007 through 2017. Designed for diesel enthusiasts who demand enhanced engine protection and performance during heavy towing, this advanced water-methanol injection system significantly lowers exhaust gas temperatures (EGTs) and intake air temperatures. By reducing heat stress on your engine, it helps maintain cleaner components, reduces emissions, and improves fuel economy.

This kit is ideal for owners who regularly tow heavy loads or drive in demanding conditions where EGTs can reach dangerous levels. The Stage 3 Boost Cooler delivers up to 65+ additional horsepower, making hill climbs and heavy hauling easier and more efficient without compromising engine longevity.

Key Features

The Snow Performance Stage 3 Boost Cooler combines cutting-edge technology with user-friendly design to optimize diesel engine performance and durability. Key features include:

• Advanced 2D mapped controller that injects water-methanol based on boost pressure and exhaust gas temperatures for precise cooling
• Reduces EGTs by 100 to 300 degrees, protecting engine components from excessive heat
• Maintains significantly colder intake air temperatures for improved combustion efficiency
• Integrated boost gauge, water-methanol controller, and EGT monitor in a single compact unit
• Non-invasive installation with no drilling or interior modifications required
• Designed to mount conveniently on the steering column or dashboard
• Helps decrease harmful emissions while improving fuel economy
• Does not leave a signature on the vehicle, preserving factory warranty coverage
• Includes a 7-gallon tank for extended, trip-ready operation

Construction & Design

Snow Performance’s Stage 3 Boost Cooler kit is built with durability and reliability in mind. The controller features robust electronics housed in a compact, weather-resistant enclosure designed to withstand harsh diesel truck environments. The included 7-gallon tank is constructed from high-quality materials to ensure long-lasting corrosion resistance and secure fluid storage. All components are engineered for seamless integration with Dodge Ram diesel engines, providing a clean and professional installation without compromising vehicle aesthetics or functionality.

Performance & Sound

By injecting a precise mixture of water and methanol into the intake air stream, the Stage 3 Boost Cooler lowers intake temperatures and exhaust gas temperatures dramatically. This cooling effect reduces the risk of engine knock and thermal stress, allowing the engine to safely produce more power. Users can expect a noticeable increase of 65+ horsepower, especially under heavy load and towing conditions. The system operates silently, maintaining the factory sound profile of your Dodge Ram while enhancing performance.

Installation & Fitment

The Snow Performance Stage 3 Boost Cooler kit is designed for straightforward installation on 2007–2017 Dodge Ram 2500 and 3500 trucks with 5.9L and 6.7L diesel engines. The controller mounts easily on the steering column or dashboard without the need for drilling or additional gauge pods, preserving your vehicle’s interior. The system is non-invasive and does not require permanent modifications, making it an excellent choice for daily-driven trucks that see frequent heavy towing. Detailed instructions are included to guide you through the installation process.

Emissions Note

For customers requiring CARB compliance, Snow Performance offers a 50-state legal version of this system under part # SNO-50100, which includes a CARB Executive Order # D-723. The Stage 3 Boost Cooler kit (SNO-510-T) does not include the CARB EO and is intended for off-road or racing use only in states with emissions regulations.

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.
