Boost Cooler Stage 2 TD Water Injection

Complete Water-Methanol Injection kit with variable injection and LCD-Display.

The Boost Cooler Stage 2 TD water-meth kit progressively injects more or less water or water/alcohol, according to boost pressure. Includes a simple handheld display screen to set the injection points which can be remotely mounted or placed in a convenient place to access based on your application.

BOOST COOLER STAGE 2 TD ADVANTAGES AT A GLANCE

Electronic Control: VC-30 controller dynamically adjusts Boost Cooler injection amount based on boost pressure.
LCD Programming Unit: Separate display with real-time boost pressure and injection data.
Performance Increase: Power and torque gains of up to 10–25%
Thermal Relief: Effectively reduces exhaust gas temperatures by up to 120°C – ideal for tuning, towing, and heavy loads.
Efficient Charge Air Cooling: Lowers intake air temps by up to 60°C without boost pressure loss like conventional intercoolers.
Fuel Savings: Reduced specific fuel consumption due to optimized combustion.
Eco-Friendly: Significantly reduces nitrogen oxides (NOx) and soot emissions under full load – perfect complement to DPF systems.
Engine Care: Cleaner combustion chamber and intake system – no oil coking or deposits.
Universally Compatible: Suitable for all turbo diesel engines up to 2.1 bar boost pressure (HDi/TDI/TDCi/TDS/... etc).
Easy Installation: Includes all required components for straightforward installation.

SNOW PERFORMANCE BOOST COOLER SYSTEMS

Maximum power and reduced emissions for your turbo diesel
The Boost Cooler Stage 2 water injection system by SNOW Performance enables a power increase of up to 10–25% in turbo diesel engines, without causing thermal overload. By cooling the intake air by up to 60°C and effectively lowering exhaust gas temperatures, thermal stress is reduced and torque is increased – also ideal for performance-tuned engines.

The new Boost Cooler Stage 2 TD system is designed for all turbo diesel engines up to 2.1 bar of boost and offers excellent value for money. Like the Stage 2.5 and Stage 3 systems, the injection quantity is electronically controlled by boost pressure and provides optimized, variable injection control compared to the Stage 1 system.

Once the previously set boost pressure is reached (set via the LCD screen), the patented high-pressure pump injects finely atomized water or a water/alcohol mix (methanol or ethanol) into the hot intake air. This evaporative cooling improves combustion efficiency and significantly reduces nitrogen oxide (NOx) formation.

Another advantage is the steam expansion effect: the evaporating water in the combustion chamber creates additional pressure on the piston, increasing torque and optimizing power output. This technology has already been successfully used in aviation to improve engine efficiency.
