AEM V3 1.15 Gallon Water Injection Kit


*Preferred part used on the MPT Ecoboost Truck*


What's changed between V2 and V3?

In testing at AEM, the V3 250cc WMI nozzle and the V2 250cc WMI nozzle both achieved a 90-degree inlet temp reduction. However, the V3 nozzle design achieved this reduction nearly 6.5 seconds faster. Think about 6.5 seconds in a racing environment. Having 6.5 seconds to get to the point where additional timing can be applied is huge. Consider that on an average sportsman drag car this can represent close to 40% of track time. On a road race car, applying more timing 6.5 seconds faster can mean a critical time to pass on a corner exit.

AEM then tested a V3 250cc injector against a V2 500cc injector to see if the larger V2 injector would improve cooling speed. The V2 500cc injector achieved nearly identical cooling speed as the V3 250cc injector, but it required almost 44% more fluid to achieve the same cooling. Less fluid used means fewer refills of your WMI tank and less money spent refilling it. Using the V2 500cc nozzle with a one-gallon tank, you will get close to 7 minutes and 50 seconds of run time at full pressure. Using the V3 250cc nozzle with a one-gallon tank, you will get 13 minutes and 30 seconds of run time at full pressure.

Plus, to top it all off, AEM has made their already heavy duty, high pressure, injection pump waterproof!




Water injection for gas engines is a proven means for effectively reducing engine inlet air temperatures and suppressing harmful detonation on forced induction and high performance naturally aspirated race engines. This allows racers to reliably increase boost and advance ignition timing -without using high-octane racing fuel- for power gains of up to 20%.

  • Boost dependent controller with on-board MAP sensor

  • Boost Safe readiness safety system

  • 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 integral conductive low-fluid sensor

  • Internally-bypassed water injection pump does not cycle on an off and provides quiet, smooth operation. It features robust construction including integral hose fittings, EPDM seals and a Santoprene diaphragm that provides consistent and reliable fluid delivery

  • LED dash light for system status

  • 20 ft. of injection tubing

The on-demand progressive controller in AEM's Boost Dependent PN30-3300 Water Injection kit


This kit bases injection flow on manifold pressure using an on-board MAP sensor (up to 35 PSI of boost) to ensure the proper amount of water injection at all points along an engine's power curve.

AEM's engineers spent extensive time developing the controller's flow control strategy for a more linear flow output delivery. This means that the flow delivery better matches an engine's need for water injection, which further optimizes charge air cooling and detonation control.

The controller design features large, turn-resistant knobs and larger numbering to easily set accurate start and full activation points, with covered status LED and test buttons for added splash resistance. A plug is integrated into the controller housing for mating to the redesigned wiring harness's positive-lock connector. The Boost Dependent controller housing has a molded-in, barbed nipple to accept a boost hose and a wiring legend on the back, integrated fuse and molded mounting tabs.

Heavy-Duty Waterproof High Pressure Injection Pump


AEM’s internally-bypassed water/methanol injection pump is waterproof and safe for mounting in loactions that are exposed the elements. It does not cycle on and off and provides quiet, smooth operation. It features robust construction including integral hose fittings, EPDM seals and a Santoprene diaphragm that provides consistent and reliable fluid delivery.






Low-Profile 1.15 Gallon Tank


The gasoline WMI tank was redesigned offering 15% more capacity compared to the previous 1- gallon design (1.15 gallons vs. old 1 gallon tank). It comes with an anti-starvation reservoir that collects fluid near the feed fitting at the bottom of the tank, and features relocated mounting holes that fit within the overall footprint of the tank.


Machined Billet Injectors and Nozzles


AEM includes one precision-machined billet injector in its gasoline Water Injection kit. It features an integral check valve to prevent unintended fluid flow. Three billet injector nozzles are included for matching water flow to an engine's horsepower output.






Simplified Wiring


AEM's Water Injection kit's wiring harness is terminated with a positive-lock connector on one end and has color-coded wires to ease installation. Both the power and ground wires for the pump are included in the harness which simplifies the wiring process and eliminates any chance of the pump accidentally activating from a short in the system. An additional wire is included for adding an optional on/off solenoid to stop fluid flow when the system is inactive.
