Snow Performance | Boost Cooler SafeInjection Pressure Switch

Water-Methanol SafeInjection Pressure Safety Switch Kit - ProLine

Protect your water-methanol injection system with smart pressure monitoring designed to detect problems before they lead to engine damage.

The SNOW Performance SafeInjection Pressure Safety Switch Kit is a dependable failsafe solution for Boost Cooler ProLine water-methanol injection systems. It continuously monitors injection pressure and helps identify common issues such as pump failure, leaking lines, clogged nozzles, or pressure loss, reducing the risk of engine damage caused by insufficient fluid delivery.

An adjustable pressure switch with a range of 35-100 PSI (2.4-6.9 bar) tracks system pressure in real time. If pressure drops below the selected threshold, the included high-intensity warning LED immediately alerts the driver. The system can also be integrated with aftermarket ECUs, electronic boost controllers, and ignition systems, allowing automatic safety actions such as timing retard, boost reduction, or activation of a safe engine map.
