Stage 2 Boost Cooler Water-Methanol Injection Kit

The Snow Performance SNO-2169-BRD is a Stage 2 Boost Cooler system engineered to enhance performance for all N54/N55 engines. This kit allows you to increase your pump gas octane by up to 25 points, leading to more efficient power production and a cooler operating engine. The system features a custom water-methanol injection throttle body spacer plate, a durable braided stainless steel line with 4AN fittings for reliable and straightforward installation. At the heart of this kit is the progressive VC-50 controller, manufactured to ISO 9001 standards. This controller proportionally manages water-methanol injection based on boost pressure, allowing for adjustable start and full injection points to match the engine's specific requirements. This proportional delivery ensures optimal cooling and performance improvements across a wide operational range, enhancing drivability. The VC-50 also functions as a 52mm gauge, integrating boost monitoring with water-methanol control. It boasts a 7-color OLED screen that displays critical information such as boost levels, injection percentage, low fluid level, secondary nozzle activation, a prime button, and two fault codes. The screen can be customized to match your OEM gauge colors or mixed and matched. This kit includes a white 5-gallon tank and stainless braided lines. It is explicitly designed for N54 and N55 engines, though a note indicates that N55 engines may require some modification for installation.
