The Snow Performance Stage 3 Boost Cooler is engineered for EFI and forced induction vehicles, delivering precise water-methanol injection based on both boost and fuel injector pulse width. This advanced two-dimensional mapping ensures optimal injection at every point in the powerband, extending control beyond simple boost reference for maximum performance and safety.

The Stage 3 controller is non-invasive and mounts easily to your steering column or dash, eliminating the need for extra gauge pods. It functions as a boost gauge, water-meth controller, and fuel system monitor in a single unit. The system is proven to reduce air intake temperatures by up to 100°F and can increase octane by up to 25 points, supporting higher horsepower and improved engine cooling.

Kit includes an adjustable Stage 3 water-meth controller, 4AN stainless braided line, and quick-connect fittings for straightforward installation. The new nozzle design ensures consistent atomization and reliability. Additional benefits include reduced exhaust gas temperatures (EGTs) and removal of carbon buildup from your engine.
