Stage 2 Boost Cooler 2005-2014 Subaru WRX STI 2.5L Water-Methanol Injection Kit

Snow Performance stage 2.5 forced induction progressive water/methanol injection kits provide increased performance with or without nitrous. Water methanol injection cools your incoming air charge and increases the total octane effect of pump gas. This allows you to run increased timing, which results in increased power and torque. When used with nitrous, the need for timing retard is greatly reduced or eliminated, and boosted applications especially benefit from reduced intake temperatures. The system includes everything needed for the installation. Order the model for your application.
