Snow Diesel Stage 2.5 Boost Cooler Kit – SNO-430
Fits: 2004–2025 Chevy Silverado / GMC Sierra Duramax (LBZ, LLY, LMM, LML, L5P)
Unlock serious gains in power and cooling with the Snow Performance Stage 2.5 Boost Cooler, engineered for Duramax-powered Silverado and Sierra trucks. This water-methanol injection system helps lower exhaust gas temperatures by 100–300°F and delivers an increase of 65+ horsepower—ideal for daily drivers and light towing setups.
The system features a VC-50 progressive controller (52mm gauge) that manages two injection nozzles, adjusting output based on boost pressure. Start and full engagement points are fully adjustable, allowing you to fine-tune the delivery curve to match your engine’s needs. The VC-50 doubles as both a boost gauge and injection controller, with a vibrant 7-color OLED display (Blue, White, Red, Yellow, Orange, Purple, Green) showing boost levels, injection percentage, secondary nozzle activation, prime status, and fault codes. Customize the screen to match your factory gauges or mix colors for a personalized look.
