Snow Diesel Stage 2.5 Boost Cooler – Braided Line Kit (2004–2025 Silverado/Sierra Duramax) SNO-430-BRD
Unlock cooler, cleaner performance for your Chevy or GMC Duramax with the Snow Performance Stage 2.5 Boost Cooler. Designed for LBZ, LLY, LMM, LML, and L5P diesel engines, this water-methanol injection system helps drop EGTs by 100–300°F and delivers a gain of 65+ horsepower—perfect for improving drivability and protecting your engine during light towing.
The Stage 2.5 kit features a progressive VC-50 controller (52mm gauge) that precisely manages two water-methanol nozzles, adjusting flow based on boost pressure. With customizable start and full boost points, you can fine-tune the injection curve to match your engine’s needs across the entire boost range.
The VC-50 doubles as a boost gauge and injection controller, with a vibrant OLED display offering seven color options (Blue, White, Red, Yellow, Orange, Purple, Green). Monitor boost levels, injection percentage, secondary nozzle activation, and fault codes—all from one sleek interface. You can even match the display to your factory gauges or mix colors for a custom look.
Includes a 7-gallon tank for easy, trip-ready installation. Ideal for daily-driven Duramax trucks that occasionally tow and need reliable EGT control.
