Snow Performance Stage 2 Boost Cooler 2015+ Subaru WRX (Non-STI) Water Injection System

The Snow Performance Stage 2 Boost Cooler (SNO-2182-BRD) is a water-methanol injection system designed for forced induction applications, specifically the 2015-2021 Subaru WRX (non-STI) and various forced induction Dodge Challenger and Charger models with 5.7L, 6.1L, or 6.4L HEMI engines. This system enhances engine performance by increasing pump gas octane by 25 points, leading to cooler and more efficient power generation. It features a custom throttle body spacer plate, braided stainless steel lines, and 4AN fittings for a secure installation. The kit includes a progressive VC-50 controller, an ISO 9001 manufactured 52mm gauge that functions as both a boost gauge and an injection controller. The VC-50 controller precisely injects water-methanol based on boost pressure, with adjustable start and full injection points. Its 7-color OLED screen provides real-time data on boost, injection percentage, low-level warnings, secondary nozzle activation, a prime button, and fault codes for comprehensive monitoring.
