The Snow Performance Diesel Stage 3 Boost Cooler is a water‑methanol injection kit engineered for turbo diesel pusher RV owners who tow heavy loads. A 2D-mapped controller meters injection based on boost pressure and EGTs to lower inlet temperatures, reduce EGTs by 100–300°, cut emissions, and improve component cleanliness and fuel economy while adding 65+ HP under heavy load. The non-invasive controller mounts on the column or dash and the kit includes a 40' harness and 7-gallon tank.
