The AEM High-Flow Low-Current Water/Methanol Injection (WMI) Solenoid Valve (PN 30-3326) provides absolute fluid control for performance water-methanol injection setups. Engineered specifically to eliminate unwanted siphoning when the WMI pump is inactive or when the injection nozzle is exposed to engine vacuum, this high-pressure solenoid valve ensures fluid flows only when commanded by your controller.

Constructed with methanol-compatible stainless steel internal components and EPDM seals, it reliably operates under continuous pressures up to 200 PSI. Featuring high-flow capabilities with minimal electrical draw, this solenoid opens rapidly without straining your electrical system or controller outputs. Its universal 1/8in-27 NPT female ports make integration straightforward into 1/4" push-to-connect or hose barb fittings.

Best Uses

1. Trunk-Mounted Reservoir Setups: Essential for rear-mounted water/meth tanks where fluid elevation relative to the nozzle can cause natural gravity siphoning into the intake manifold.
2. Direct-to-Intake / Post-Throttle Body Injection: Prevents vacuum draw from sucking fluid past the check valve during idling or high-vacuum engine deceleration.
3. High-Boost Forced Induction Engines: Ideal for turbocharged or supercharged vehicles requiring precise, instantaneous WMI activation under boost conditions.
4. Multi-Nozzle & Direct Port WMI Systems: Serves as a fast-acting shutoff valve across primary or secondary injection lines to eliminate fluid drip between stages.

Features

1. High-Pressure Capability: Engineered to withstand and operate seamlessly under fluid pressures up to 200 PSI.
2. Low Current Draw: Designed with an efficient coil design that consumes minimal amperage, protecting controllers and engine management outputs.
3. Methanol-Resistant Construction: Built with stainless steel internals and durable EPDM seals compatible with high-concentration water/methanol mixtures.
4. Standardized Fittings: Equipped with 1/8in-27 NPT female inlet/outlet ports for easy plumbing with standard push-to-connect fittings or braided lines.
5. Fast-Acting Response Time: Ultra-responsive solenoid coil ensures immediate open/close action, preventing lag or post-injection fluid spray.

Benefits

1. Eliminates Unwanted Siphoning: Positively seals the fluid line when de-energized, stopping gravity or vacuum from pulling fluid into the engine when off.
2. Protects Engine from Hydro-Locking: Prevents accidental fluid pooling inside the intake manifold during off-boost cruising or parking.
3. Instantaneous Spray Shut-off: Eliminates residual pressure bleed and post-spray dripping at the nozzle for cleaner combustion transitions.
4. Universal System Compatibility: Works seamlessly with AEM Water/Methanol Injection Kits as well as third-party aftermarket WMI setups.
5. Enhanced System Reliability: Heavy-duty, corrosion-resistant build provides long service life under high heat and harsh chemical environments.
