The Snow Performance Stage 3.5 Boost Cooler® brings true 2D mapped water-methanol injection delivery to your DI (direct fuel injected) and forced induction (turbocharged/supercharged) vehicle. The Stage 3.5 creates a 2D injection map based off boost and fuel pressure sensor input to deliver an 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 3.5 Boost Cooler® controller is designed to mount like a traditional gauge pod. 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 3.5 water-meth controller (VC-100), 4AN fittings, and stainless steel braided line to mount pump/tank in engine bay of vehicle. For trunk mount options see Part# SNO-40014-BRD, SNO-40012-BRD.
