*** NEW! - ProLine Version ***
Water Methanol Injection for all turbo-/supercharged engines up to 2.1 bar of boost pressure.
This water/meth kit comes with variable Injection (VC-30) and 300PSI/20bar Pumpsystem and ProLine steel flex lines. It progressively injects more or less water or water/alcohol, according to manifold boost pressure. Includes a simple handheld display screen to set your injection points.
Please Note: You will require the Snow Performance BMW Water Methanol Injection Solenoid Valve Upgrade if the reservoir is to be installed in the back of the car (rear boot).
Snow Performance Boost Cooler Systems

Boost Cooler water injection can achieve a power increase of up to 10-25% in turbo and supercharged engines without thermally overloading the engine. The charge air temperature is lowered by up to 60°C, the combustion chamber is cooled and the thermal load on already tuned vehicles is effectively reduced.
Water or water/alcohol (methanol or ethanol) is injected at high pressure into the hot charge air in a finely atomised form as soon as the desired starting charge pressure is reached. The evaporating liquid achieves an extremely effective charge air and intercooling, which, among other things, prevents uncontrolled combustion ("knocking"). The effect is demonstrably comparable with 116 octane racing petrol.
The Boost Cooler is unsurpassed in atomisation! The liquid is swirled inside the Hyper-Sonic atomiser nozzle at supersonic speed before being forced through the Venturi orifice. With the included Dual Stage Upgrade, 2 atomiser nozzles are used to inject as early as possible with the primary nozzle and to achieve maximum cooling and performance in peak loads with the switched-on 2nd nozzle.
VC-30 Controller Inc. Map-sensor
The included control unit varies the injection quantity, with a reaction time of 1.5msek, flexibly to the boost pressure. The settings on the LCD screen can be made within a few seconds without prior knowledge. You only set the boost pressure (start/full) - the system does the rest for you.
The VC-30 control unit can be placed in the engine compartment or inside the vehicle, protected from splash water. The LCD display can be installed in the field of view if required and provides general information about the status of your system (boost pressure display as well as pump performance).
ProLine
Temperature and pressure resistant Boost Cooler steel flex braided line - ProLine Series. High-quality steel braided line for your Boost Cooler water injection of the ProLine series. - There is hardly a better line for use in water-methanol injection systems. Steel flex lines from SNOW Performance are quality products at the highest level. Ideally suited for high demands on appearance and safety, in motor sports as well as marine and aviation applications.
Performance
With the Boost Cooler, you can achieve a power increase of about 10-25%, even with already tuned turbo and supercharged engines. The optimum cooling compensates for typical power losses at higher outside temperatures. In addition, deposits in the combustion chamber and intake tract are reduced.
Optimal Cooling
In contrast to a conventional intercooler, the charge air can be lowered below the ambient temperature! In addition to the outstanding efficiency, there is no loss of boost pressure as with conventional performance intercoolers. The Boost Cooler efficiently cools the intake air and combustion chamber temperature ("in-cylinder-cooling"). The addition of alcohol (preferably methanol or inexpensive bio-ethanol) additionally increases efficiency and counteracts lean running.
Octanebooster
In combination with super petrol and a water/methanol mixture, you achieve a comparable effect as with 116-octane racing petrol. This also allows you to dispense with the considerably more expensive Shell "V-Power", "Ultimate 100", etc. and drive only with conventional super gas.
Easy Installation
To ensure a smooth installation, all connection materials are included in the scope of delivery of the system. The detailed installation instructions in German, with many illustrations and a clear structure, guide you step by step through the installation process.
Less Consumption - Less CO2
The better efficiency improves fuel economy. As a rule, fuel savings are in the range of 5-15% depending on the vehicle, driving style and use (e.g. tractors).
The NREL test result clearly shows that NOx emissions are significantly reduced with the Boost Cooler System activated. As a positive side effect, the DPF regeneration cycles are extended due to the lower pollutant emissions.
Less Deposits in the Combustion Chamber
The combustion chamber of your engine remains free of deposits, the heat dissipation, e.g. at the exhaust valves, remains optimal. Oil coking is reduced and prevented.
Motorsports Know-how
As an OE supplier and through its activities in a wide range of motorsport areas, SNOW Performance proves the quality and durability of the high-quality water injection systems "Made by SNOW PERFORMANCE".
Pressure Diaphragm Pump
SNOW Performance 300 PSI UHO methanol injection pumps offer unmatched pressure, technology and reliability. All 300 PSI pumps are made in the USA and individually tested before shipping to ensure quality and reliability. Although similar looking pumps are available, they do not have the features of our SNOW Performane pumps.
Double EPDM seals ensure durability and higher pressure. Proprietary internal wiring offers lower power consumption than similar looking pumps. Integrated thermal protection circuitry allows the pump to operate constantly without damaging pump internals.
Hyper-Sonic Injection Nozzles
The SNOW Performance HyperSonic atomiser nozzle is the world's best-selling and most advanced water/alcohol injection nozzle. The liquid is swirled inside the patented 2-chamber nozzle at supersonic speed before being forced through the Venturi orifice. This creates droplets or mists as fine as 20µ (microns) with enormous cooling potential.
The principle of evaporative cooling is a highly efficient technology and effectively reduces the intake or charge air temperature. Likewise, evaporation processes within the engine reduce the thermal load.
3l Reservoir with Fluid Level Switch
Boost Cooler water injection 3l tank with separate level indicator and warning LED (orange) for installation in the vehicle interior. With the "reserve light" you can be sure never to operate your water-methanol injection without sufficient fluid. Completely incl. connection for 1/4" pressure line.
To extend the range of the water injection, you can upgrade this system to a tank with a capacity of 9.5l or 26.5l. To do this, simply configure the desired tank size.
Universal Fitment
Including All turbo-/supercharged engines up to 2.1 bar/30 psi of boost pressure. #
This includes BMW engines; N20, N54, N55, S55, N63, n63tu, M57, B38, B48, B58, S63, and s63tu.
