This item cannot be shipped to California due to Carb regulation with CA. Snow Performance has combined performance, quality, and ease of installation in this new water-methanol injection kit designed for all Chevy / GMC LBZ / LLY/ LMM/ LML / L5P Duramax Ford owners who demand colder EGTs while towing heavy loads. The Diesel Stage 3 Boost Cooler utilizes a 2D mapped controller that commands injection based on boost pressure and EGTs (exhaust gas temperatures) to maintain extremely cold air inlet temperatures, 100-300 EGT decreases, decreased emissions, cleaner engine components, and increased fuel economy all while giving 65+ HP to help pull large hills with easy effort while towing. A must have for the diesel enthusiast that is concerned about the longevity of his truck that sees heavy towing. None invasive, the Diesel Stage 3 Boost Cooler? controller is designed to mount on the steering column or the dash so no drilling/marring of the interior needs to take place or additional gauge pods need to be purchased. Functions as a boost gauge, water-meth controller and EGT monitor all in one! Concerned about warranty? The Snow Performance Stage 3 does not leave a signature on the vehicle leaving your diesel truck with its warranty intact. 7 Gal Tank included for trip ready installation. Recommended for all daily driven Chevy /GMC LBZ / LLY / LMM / LML / L5P Duramax owners that see heavy towing where EGTs become dangerously high. Need a CARB E.O.# for your state? No problem! See part# SNO-50100 for 50-State legal system (C.A.R.B E.0.# D-723)
