Emissions Warning: This product is not designed for public highway or street use, and is only legal for formally sanctioned race use on a racing vehicle that may never be used on a public highway or street.

Water / methanol injection is designed to allow higher boost and more advanced timing on forced induction Honda Civics, to get significantly more power while still utilizing pump gas. Containing all the necessary parts for a safe and reliable install, these AEM water/meth kits come with most everything needed to dramatically reduce your intake temps and increase the detonation threshold of your Honda Civic.

How does water / methanol Injection work? The major benefits of water / methanol injection are due to the cooling effects of evaporation and the high octane rating of the mixture during combustion. The water / methanol mixture is injected through a small nozzle downstream of the turbo and after any intercooler being used, which creates a fine mist of cool liquid in the intake tract. The heat in the compressed air causes the liquid to evaporate which absorbs heat from the surrounding air. This cooler air charge is now denser than it was when hot, and also contains a mixture of methanol which will raise the effective octane rating once it reaches the combustion chamber along with the fuel injected normally. This allows the ignition timing to be advanced while preventing pre-ignition of the air/fuel mixture.

Benefits of Water / Methanol Injection:
  • Reliably increase boost and advance ignition timing without using high-octane racing fuel. Power gains of up to 20%!
  • Reduced carbon deposits in the intake tract.
  • Lower intake temps, resulting in denser air charges.
  • Increases knock resistance.
  • Slight increases in fuel economy are possible.
  • Can add power to any forced induction or NA setup with proper tuning.
Kit Contents:
  • High pressure recirculation style (non-pulsing) 200 PSI weatherproof WM pump.
  • Tanks have integrated Level Sensor (except on the No Tank Kit).
  • Progressive Injection Control Module with Boost Reference (max at 35 PSI of boost).
  • Super efficient V3 jets / injectors with Swirl Generators for 250cc, 500cc, and 1000cc of flow.
  • Injection Check Valve.
  • 20 ft nylon injection hose and fittings.
  • 60 inch vacuum hose.
  • Mounting hardware and instructions.
  • The optional Dual Throttle Body Nozzle Kit allows the standard water / methanol kit to be used on vehicles with dual throttle bodies. It includes an additional nozzle body, tee fitting, hose, and V3 jets / injectors (with Swirl Generators) for 250cc, 500cc, and 1000cc of flow.
We recommend using the optional Inline Injection Filter to prevent any pump, check valve, or nozzle clogging from debris that may get in the tank.

IMPORTANT: Water / methanol Injection is an advanced power adder and should only be used in vehicles tuned to run safely with the system in place. Professional installation and tuning is highly recommended.

Universal (Version 3) (Forced Induction) (No Tank) AEM Water / Methanol Injection Kit (V3)
More Info: This is a Universal application. Please read all notes including the product description to determine if this part will work for you. DOES NOT INCLUDE A TANK (you must use your own - your factory windshield washer reservoir may work for this). For forced induction engines with up to 35 PSI of boost. Uses boost-dependent controller with on-board MAP sensor. Version 3 (V3) features simplified wiring, much more efficient jets / injectors with swirl generators for 250cc, 500cc, and 1000cc, and many more small improvements.
$559.95$496.95
Universal (Version 3) (Naturally Aspirated) (1.15 Gallon Tank) AEM Water / Methanol Injection Kit (V3)
More Info: This is a Universal application. Please read all notes including the product description to determine if this part will work for you. For naturally aspirated engines. Uses multi-input controller for 0-5v factory MAF sensor or 0-5v external MAP sensor (allowing this kit to also be used on very high boost applications above 35 PSI). Version 3 (V3) features an optimized tank design with anti-starvation reservoir and more accurate low level sensor, simplified wiring, much more efficient jets / injectors with swirl generators for 250cc, 500cc, and 1000cc, and many more small improvements.
