The Snow Performance Stage 2 Diesel Boost Cooler for Chevy/GMC Duramax engines (LBZ/LLY/LMM/LML/L5P) reduces EGTs and can add horsepower by delivering progressive water-methanol injection across the boost range. The VC-50 controller proportionally manages two nozzles by boost pressure, with adjustable start and full points for tuning. The kit includes a seven-gallon tank and is recommended for daily-driven Duramax trucks that see light towing.
