Water/Methanol Injection. Improve the power and performance of your turbocharged EcoBoost Mustang with water/methanol injection system from Snow Performance. The Stage 3 Boost Cooler cools the combustion chambers of an internal combustion engine by adding a fine spray of a water/methanol mix to the incoming air-fuel mixture. This will not only help reduce intake temperature, but it will also help improve the octane rating of your fuel. With a higher octane rating you will be able to increase ignition timing for even more rear wheel horsepower and torque.

No Laptop Needed. The heart of the Snow Performance Stage 3 Boost Cooler is the Digital Variable Mapping Controller, which creates a 2D injection map based off boost and fuel pressure sensor voltage. The Digital Variable Mapping Controller operates 2 Hyper-Sonic™ Nozzles independently of each other to provide the precise amount of water/methanol needed at all engine RPMs. The Stage 3 Boost Cooler can quickly and easily be dialed in by the driver using the included tuning guide, with no need for a laptop or computer programmer.

  • Performance gains when using the Snow Performance Stage 3 Boost Cooler will depend on a number of factors, including boost pressure, altitude, ambient air temp, and the tune you are using. We have seen gains between 30-50 horsepower as average, but gains vary with different factors.

Does this kit come with mounting brackets to mount the reservoir to the front of the engine block? Asked because I looked at the customer picture and saw there was a mounting bracket for the reservoir but was not sure if he made that himself or it is included.


  • The Snow Performance Stage 3 Boost Cooler will not include a bracket to mount this to the engine. The bracket used in the customer submitted images is a custom made bracket.

    By far the most pricey kit ive seen on the market. Like any other methanol injector it takes a bit of time to install and ALOT of patience. Had trouble finding a place to mount the 3qt reservoir; ended up making a bracket to install on the engine between the airbox right in front of the pully. Installed the pump below the sway bar pointing towards the front of the car. I'd recommend using bolts instead of the screws they give you. Also, a lift would make this job alot easier.
