Stage 2.5 Boost Cooler Water-Methanol Injection System

The Snow Performance Stage 2.5 Boost Cooler is a water-methanol injection system designed to optimize performance in forced induction engines by effectively increasing pump gas octane by up to 25 points. By cooling intake air temperatures, this system helps prevent detonation and allows for more aggressive tuning to unlock hidden horsepower and torque. The kit comes equipped with an Ultra High Output (UHO) pump, a 3-quart reservoir, a digital variable controller, and two injection nozzles. It utilizes stainless steel braided lines and 4AN fittings for enhanced durability and reliable fluid delivery under high-boost conditions. This system is specifically tailored for 2006-2014 Subaru WRX and 2004-2015 Subaru STI models. Professional installation may be required for optimal setup and to ensure compatibility with your specific vehicle configuration. Please note that this kit may require professional modifications to ensure a perfect fit depending on your specific engine bay layout.
