Snow Performance Stg 1 Boost Cooler Water Injection Kit TD (w/SS Braided Line & 4AN Fittings)

The 300 PSI UHO pump and dual Hypersonic nozzles in this Snow Performance Stage 1 Boost Cooler kit are designed to precisely deliver a water-methanol mixture to your diesel engine. This system activates once your turbo reaches 30 PSI of boost, helping to lower exhaust gas temperatures (EGTs) and increase horsepower. It’s a popular choice for high-boost and competition diesel applications where managing heat under heavy throttle is critical for performance and engine longevity.

This kit includes a 3-quart reservoir with a high-flow check valve to ensure consistent delivery and prevent backflow. The braided stainless steel lines and 4AN fittings offer a durable and leak-resistant connection, suitable for the demands of a diesel engine bay. An adjustable boost pressure switch lets you fine-tune when the system engages, and the included LED monitoring system keeps you informed of its operation. Snow Performance manufactures this kit in the U.S.A., using materials that are 100% methanol resistant for reliable performance.

For installation, you'll want to ensure you have the necessary tools to tap into your boost line and mount the components securely. The system is designed to be race-ready, offering a significant horsepower increase while helping to keep your engine temperatures in check during demanding use.
