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

The braided stainless steel lines and 4AN fittings in this Snow Performance Stage 2 Boost Cooler kit are a key detail, showing the focus on reliability and ease of installation for your 2015-2021 Subaru WRX STI. This system is designed to increase your pump gas octane by up to 25 points, allowing your engine to run cooler and make more power efficiently. It's a smart way to get more out of your forced induction setup without needing a separate tank, making it a cleaner install.

At the heart of this kit is the VC-50 controller, which also functions as a 52mm boost gauge. This advanced controller proportionally injects more or less water-methanol based on your boost pressure. You can adjust the start and full injection points to perfectly match your engine's needs, ensuring accurate delivery across a wide range of operation. The controller features a 7-color OLED screen that displays boost levels, percentage of injection, low fluid warnings, and even fault codes, letting you keep an eye on critical engine parameters and tailor the display to your dash.

This kit includes a custom water-methanol injection throttle body spacer plate, ensuring a straightforward installation. While this kit is designed for enhanced performance and cooling, please note that it is not CARB approved and cannot be shipped to California. For optimal performance and safety, always refer to the manufacturer's installation instructions and ensure all components are correctly installed and adjusted for your specific vehicle.
