AEM V3 Water/Methanol Injection Kit with Multi-Input Controller, Part Number 30-3350

Water/methanol injection for forced induction (turbocharged or supercharged) gas-powered race engines is a proven means for effectively reducing engine inlet air temperatures and suppressing harmful detonation. This allows racers to reliably increase boost and advance ignition timing-without using high-octane racing fuel-for power gains of up to 20%. AEM's Water Injection Kits utilize robust hardware and deliver more advanced features than any other comparably priced water/methanol injection system. V2 Water/Methanol Injection Kit, Multi Input Controller - 0-5v/MAF Frequency or Voltage/Duty Cycle/Ext MAP, 200psi WM Pump, 1.15 Gallon Reservoir, Conductive Fluid Level Sensor Boost Dependent and Multi-Input (0-5v/frequency) progressive controller designs feature large adjustment knobs, integrated plug for harness connection, integrated fuse, covered status light and test button for enhanced splash resistance and mounting tabs Wiring harness is terminated with a positive-lock connector on one end with color-coded wires to ease installation, integrated pump ground circuit and additional wire for optional on/off fluid solenoid "Boost Safe" failsafe output included (for complete failsafe under all conditions, see our Water/Methanol Failsafe Device) Heavy-duty high-pressure injection pump features integral fittings, a Santoprene diaphragm and EPDM seals to resist corrosion. Our pump maximizes line pressure for optimum atomization and its quiet, smooth operation is almost undetectable Precision-machined billet-aluminum injector with integral check valve Three interchangeable injector nozzles to cover a wide variety of HP levels (250cc/min, 500 cc/min & 1,000cc/min) 1.15-gallon tank with anti-starvation reservoir, integral conductive low-fluid sensor and positive lock connector (tank-less systems available) 20 feet of injection tubing included LED dash light for system status and low fluid warning

• Terminated harness features positive lock connector with integrated pump ground circuit and additional wire for optional on/off flow solenoid
• One machined billet injector with integral check valve to prevent unintended flow
• Recirculation-style pump with integral fittings for quiet operation
• LED dash light for system status and low fluid warning
• Includes "Boost Safe" readiness failsafe system
• 20 ft. of high-pressure Nylon injection tubing

The AEM V3 Water/Methanol Injection Kit is designed for turbocharged and supercharged gasoline race engines that need lower intake air temperatures and improved detonation control. By injecting a controlled mixture of water and methanol, the system helps support increased boost and more advanced ignition timing without relying solely on high-octane racing fuel. Depending on the engine combination and calibration, this can contribute to power gains of up to 20 percent.

This AEM system uses a multi-input progressive controller compatible with 0-5V signals, MAF frequency, voltage or duty-cycle inputs, and external MAP signals. Its boost-dependent operation, large adjustment knobs, integrated fuse, covered status light, test button, and mounting tabs support straightforward installation and reliable adjustment. The included 200 psi pump is built with a Santoprene diaphragm and EPDM seals for corrosion resistance, while integral fittings and recirculation-style operation help provide quiet, consistent fluid delivery.

The kit includes a precision-machined billet-aluminum injector with an integral check valve and three interchangeable nozzles for a broad range of engine outputs. A 1.15-gallon reservoir features an anti-starvation design and conductive low-fluid sensor, while the LED dash light provides system status and low-fluid warnings. The terminated wiring harness uses a positive-lock connector, color-coded wires, an integrated pump ground circuit, and an optional on/off solenoid wire. AEM's included Boost Safe readiness failsafe helps protect the engine if the system is not ready. This product is intended for off-road and racing applications and is not CARB approved.
