Stage 1 Boost Cooler Water-Methanol Injection System

The Snow Performance Stage 1 Boost Cooler is a water-methanol injection system designed for forced induction applications, whether fuel-injected or carbureted. This system provides basic on/off control, activating when the user-adjustable boost switch reaches a set point and injecting a consistent amount of fluid. It's an effective solution for vehicles looking to enhance octane and achieve a cooler intake charge, suitable for low to medium boost setups. The kit includes an Ultra High Output (UHO) pump, a 3-quart reservoir, two nozzles to accommodate a range of horsepower outputs, all necessary hardware for installation, and comprehensive instructions. Optional upgrades such as a low-level indicator with an LED and an EZ installation grommet, and a solenoid upgrade to prevent siphoning or gravity flow, are available. This kit is compatible with a wide array of Audi models, including various A3, A4, A5, S4, and S5 configurations across multiple model years and engine types such as 1.8T, 2.0T (FSI and TSI), 2.7T, 3.2L V6, 3.0T, and 4.2L V8 engines. Fitment is specific to particular engine and drive configurations within these model ranges.
