Product Description

The Snow Performance SNO-81083-BRD Low-Pressure Safety Switch & Gauge Kit is engineered for high-performance vehicles equipped with water-methanol injection systems. Its primary function is to monitor the pressure between your W/M pump and injection nozzles, alerting you or shutting down boost/timing if the system falls below safe operating pressure (35-100 PSI adjustable).

This universal kit features a stainless-braided -4 AN hose connection, compact inline manifold, a built-in pressure gauge, and LED warning light. Ideal for custom installations where failing to deliver W/M can cause lean or detonation conditions, this kit provides a vital safety layer. Mounting is flexible, wiring is suitable for interfacing with your ECU or boost controller, and it ensures your high-boost, high-octane, or methanol/E85 system remains protected.

Because this product is universal and not tied to specific vehicle years or trims, it must be installed by someone familiar with W/M plumbing and system integration. Verify your line size, nozzle pressure, pump output and wiring before purchase. Ensure you calibrate the switch to your setup and confirm safe operation under load.
