Snow Performance BMW Water Methanol Injection Solenoid Valve Upgrade - Part Number SP30105
Protect your BMW engine and your water methanol system with the Snow Performance Solenoid Valve Upgrade SP30105. This high-flow, stainless-steel, methanol-safe solenoid is designed to deliver ultimate security for any BMW water methanol injection setup. It prevents unwanted siphoning and gravity feed, keeps injection clean and controlled, and ensures the line to the injector only opens when injection is enabled. If you run a rear-mounted reservoir, have injection points under vacuum, or your nozzle sits lower than the tank, this anti-siphon solenoid is a must-have upgrade for reliable water meth performance.
Compatible with all Snow Performance Water Methanol Injection Kits and Upgrades, this is the highest flowing water methanol solenoid on the market. We use it on our own builds and our customers love the peace of mind and consistency it delivers. Fit it once and drive hard with confidence.
