Snow Performance SNO-430-T Diesel Stage Boost Cooler Water-Methanol Injection Kit - 2

The Snow Performance SNO-430-T Diesel Stage 2 Boost Cooler is a complete water-methanol injection system designed specifically for Chevy and GMC Duramax diesel engines, including LBZ, LLY, LMM, LML, and L5P platforms. This advanced injection kit safely increases horsepower and torque while simultaneously lowering exhaust gas temperatures (EGTs) and reducing harmful emissions.

Key Features:

• Progressive water-methanol injection system that activates based on boost pressure
• Digital controller with internal MAP sensor for precise fuel delivery monitoring
• High-temperature red nylon tubing rated for under-hood durability
• Quick-connect fittings for simplified installation and maintenance
• High-flow injection nozzle optimized for diesel applications
• Low fluid warning light to prevent dry running
• Complete kit includes reservoir, pump, controller, wiring harness, and all mounting hardware

Water-methanol injection works by spraying a fine mist into the intake air stream, where it evaporates and absorbs heat. This cooling effect increases air density for improved combustion efficiency while the methanol component provides additional octane boost. The Stage 2 system is ideal for modified diesel trucks running increased boost levels, offering measurable performance gains and enhanced engine protection under demanding conditions.
