The Snow Performance Stage 3 Boost Cooler® brings true 2D mapped water-methanol injection delivery to your DI (direct fuel injected) and forced induction (turbocharged/supercharged) vehicle. The Stage 3 creates a 2D injection map based off boost and fuel pressure sensor input to deliver a extremely accurate amount of water-methanol when the engine needs it most. Bringing fuel pressure into the mix allows the injection curve to be extended past specific boost points for greater range/control. None invasive, the Stage 3 Boost Cooler® controller is designed to mount on the steering column or the dash so no additional gauge pods need to be purchased and functions as a boost gauge, water-meth controller and fuel system monitor all in one! Proven to reduce the air inlet temperature by up to 100 degrees and increase octane by 25 points for maximum HP and cooling . Comes with adjustable Stage 3 water-meth controller, 1/4" High Temp Nylon line and easy to install quick-connect fittings.
