Show original supplier description

The AEM Water/Methanol Solenoid (30-3326) is a critical component for upgrading your existing water/methanol injection (WMI) system. This 2-way, normally closed 12V valve is constructed with a durable stainless steel body, ensuring longevity in demanding applications. Boasting high-flow capabilities of 3,600cc/min, this solenoid also features an impressively low current draw of only 0.75A, minimizing electrical load on your system. With a robust pressure rating of 200 psi and standard 1/8in NPT ports, it is designed for reliable integration into most WMI setups. This AEM solenoid is explicitly legal for sale or use on Racing Use Only Vehicles. Racing Use Only Vehicles are defined as those used exclusively for competition, not registered for street use, and never operated on public roads. Other compatible accessories from AEM include inline fluid filters, flow gauges, and nozzle/jet kits.
