Product Details
Brand: AEM Engineering


The AEM Water Injection Kit is a safe and economical way to reduce air inlet temperatures to increase boost pressure for more power. Lower air inlet temperatures allow users to advance timing without having to run higher-octane fuel. This is the most complete kit available on the market straight out of the box- no additional parts required.


  • This kit includes everything you need for installation
  • Progressive, controller-driven 200 PSI pump
  • One-gallon tank with integral fluid level sensor
  • Dash light for system status and low fluid warning
  • Alcohol Compatible (up to 50% in solution with water)
  • Progressive controller, provides boost-dependent variable flow
  • Output provided to either decrease timing or boost if the system runs out of fluid or detects an error
  • Includes three jets to match your power requirement

Optional AEM WMI Solenoid:

Although this Solenoid is optional, the AEM WMI Kit already come pre-wired for its usage. However, this is 100% needed when mounting the injection nozzle lower than the reservoir, or it is also recommended if the reservoir will be rear-mounted (to prevent gravity flowing). It is also used to prevent siphoning when the injection nozzle is mounted after the throttle body (or carburetor) and is exposed to vacuum.

  • High flow rating (3600 cc/min @ 150 psi)
  • Low current draw (0.75A @ 13.5V)
  • No additional relay required
  • Standard 1/8”- 27 NPT inlet/outlet with included ¼” push-to-lock hose fittings for easy installation
  • Fast response time
  • Tested to 200 PSI
  • Stainless steel enclosure and internals with EPDM seals for corrosion resistance
  • Flying leads simplify connection with user desired connector

NOTE: Some people have complained that their Water/Methanol Injection Kit is going through A LOT of fluid - This is a sign that boost siphoning/gravity flow is most likely occurring. This products provides peace of mind, ensuring that the methanol mixture will only be pumped/sprayed when it's supposed to, (via the specified controller settings), but it is not 100% needed if instructions are followed correctly.

Optional AEM WMI Inline Injection Filter:

The AEM Water/Methanol Injection Filter is an in-line filter that uses a micronic mesh screen to filter particulates as small as 40 microns. This allows a cleaner flow of water/methanol to be passed into the engine, not only protecting the internals of the engine itself, but also the working parts of the water/methanol pump, too. Run the AEM Water/Methanol Injection Filter in-line before the pump to protect both pump and engine.

If you are using a Water/Methanol Injection System it may greatly increase pump life to use a water/methanol filter. The AEM Water/Methanol Injection Filter prevents foreign particles as small as 40 microns from clogging or damaging pumps, injection nozzles check valves or flow sensors. The AEM Water/Methanol Injection Filter uses fittings for use with 1/4" OD nylon tubing, so it fits most Water/Methanol injection kits on the market today!


  • Simple to install, takes less than a minute!
  • Fits virtually every Water/Methanol system on the market
  • Polypropylene housing - rugged material that is compatible with high concentrations of methanol
  • Completely Serviceable Assembly - can be disassembled, cleaned and reused for a long service life
  • Stainless Steel mesh strainer - AEMs custom mesh strainer filters down to 40 microns - MUCH smaller than similar filters
  • Large Filtering Area assure long service life and does not significantly reduce flow
  • Micronic Mesh Screen out-performs sintered filters in both filtering and serviceability
