Snow Performance Water-Methanol Injection Systems
Snow Performance Water-Methanol Injection Systems
Snow Performance specialises in water-methanol injection (WMI) for turbocharged engines. Their systems inject a finely atomised mist of water and methanol into the intake tract. The mist evaporates to lower intake air temperatures and raise effective octane, which helps suppress detonation. This collection covers Snow Performance pumps, tanks and related water-methanol hardware.
Shop by Product Type
- Pumps: high-pressure pumps such as the Snow Performance 300 UHO Pump – Extreme Environment (Quick Connect).
- Tanks: reservoir upgrades such as the Snow Performance 10 Gal Water–Methanol Tank Upgrade in high temp nylon. It is supplied with brackets, solenoid, hose and fittings.
- Kits and controllers: Snow Performance Stage 2 and Stage 3 water-methanol injection systems with progressive controllers.
- Nozzles: atomising nozzles that deliver a fine mist into the intake.
- Solenoids and fail-safes: hardware that helps prevent siphoning and protects the engine if fluid runs low or a line becomes blocked.

Choosing the Right Part
Start by deciding whether you need a complete system or a component for an existing one. Stage 2 and Stage 3 systems differ mainly in how injection is controlled. Stage 3 controllers are load-sensing and map the injection curve to a boost or MAF signal.
When choosing a replacement pump, check its connection type and variant. For example, the 300 UHO Pump listed here is the Extreme Environment version with Quick Connect fittings.
When upgrading a tank, confirm the capacity and what is included. The 10 Gal Tank Upgrade comes with brackets, a solenoid, hose and fittings.
Installation & What You'll Need
A water-methanol system must be matched to the engine's calibration. A custom ECU tune is required to safely use the extra knock resistance.
Plan for these items:
- a suitable mounting location for the tank and pump
- routing for the hose to the nozzle
- a solenoid to prevent siphoning
- a fail-safe arrangement in case fluid runs low or a line is blocked
Installation by a professional is recommended.
FAQ
How does water-methanol injection increase power?
It works through cooling and octane. Evaporating water absorbs heat and lowers intake air temperatures. Methanol raises effective octane and suppresses knock. Together, these allow a tuner to safely increase ignition timing and boost.
What fluid should I use in a Snow Performance system?
Many users run a 50/50 mix of distilled water and pure methanol. The water provides the cooling effect. The methanol adds octane and helps stop the mixture from freezing.
Is a tune required for water-methanol injection?
Yes. A custom ECU calibration is needed to gain the performance benefit and keep the engine safe. It lets the tuner adjust timing and fuelling for the injected mixture.
Can I use water-methanol injection on a daily driver?
Yes. Progressive controllers only activate the system above a set boost threshold, so fluid is not used during normal cruising. A fail-safe is recommended for street use.
