Product Overview
AEM V3 Water/Methanol Injection Kit 30-3300
Water/methanol injection sprays a fine mist into the intake tract under boost. As it evaporates it pulls heat out of the charge air, lowering intake temperatures and increasing knock resistance, which gives a tuner room for more timing or boost on pump fuel. The AEM V3 kit 30-3300 is a universal system for forced induction engines, built around a boost-dependent controller with an on-board MAP sensor that starts and ramps injection according to boost pressure.
What’s in the kit
- Boost-dependent controller (up to 35 psi) with integrated fuse and mounting tabs
- 1.15 gallon reservoir with built-in conductive low fluid level sensor
- Quiet recirculation-style pump with integral fittings
- Machined billet injector with integral check valve
- Three interchangeable nozzles: 250, 500 and 1,000 cc/min
- 20 ft of high-pressure nylon injection tubing
- Terminated wiring harness and LED dash light for status and low fluid warning
Safety features
AEM’s Boost Safe output triggers if the system detects a short, a loss of continuity, high or low voltage, or low fluid. Wired into an ECU or boost controller, it lets you pull boost or switch maps if injection fails, which is the main reason to choose a proper failsafe system over a basic kit. The controller has large numbered adjustment knobs, a covered status LED and a test button. The harness also includes a spare wire for an optional on/off solenoid, which is sold separately.
Fitting and tuning
The kit is universal, so the tank, pump and injector positions are chosen to suit your car. The injector is normally mounted in the charge pipe after the intercooler and before the throttle body. Start with a small nozzle and conservative onset settings, check the system with the test button for leaks, and have the engine mapped to take advantage of the extra knock margin. Full specifications are on the AEM 30-3300 product page. AEM covers the kit with a one-year manufacturer warranty.
