SNOW PERFORMANCE
BOOST COOLER
SYSTEMS

Maximum power and reduced emissions for your turbo diesel
The Boost Cooler Stage 1 water injection system from 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 temperatures, thermal stress is reduced and torque is increased – ideal even for performance-enhanced engines.

As soon as the preset boost pressure is reached, the patented high-pressure pump injects finely atomized water or a water/alcohol mixture (methanol or ethanol) into the hot intake air. This evaporative cooling leads to improved combustion efficiency and significantly reduces the formation of nitrogen oxides (NOx).

Another benefit 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.

BOOST PRESSURE SWITCH
INCL. RELAY

The desired injection start point is easily set using the included boost pressure switch. Once the preset boost pressure is reached, the Boost Cooler activates (on/off). Unlike the Boost Cooler Stage 2 and Stage 3 systems, the injection quantity in the Stage 1 system is controlled without electronic regulation.

This makes the kit particularly well-suited for engines with a constant load profile, such as in combined heat and power units (CHP), marine diesels, or stationary applications. Installation in passenger cars or commercial vehicles is also easy and worthwhile.

PERFORMANCE

With the Boost Cooler Stage, you achieve a noticeable power increase of up to 10–25% – even on already tuned turbo diesel engines. Injecting a finely atomized water or water/alcohol mixture into the intake air improves oxygen density in the combustion chamber. The result: more efficiency, more torque, and clean, controlled combustion.

OPTIMAL COOLING

Water injection effectively cools the intake air via evaporative cooling, reducing intake temperatures by up to 60°C. This allows for higher air density and more oxygen for combustion. Additionally, in-cylinder temperatures are lowered, which improves power and efficiency.

LOWER CONSUMPTION –
LESS NOx

Integrating water-methanol injection into turbo diesel engines enables significant reductions in nitrogen oxides (NOx) and soot emissions. Studies show NOx can be reduced by up to 30% and soot by up to 70%. At the same time, fuel efficiency improves, with savings of up to 5–15%, depending on vehicle type, driving style, and usage conditions (e.g., towing).

LESS COMBUSTION CHAMBER DEPOSITS

Cleaner combustion with the Boost Cooler produces fewer soot particles and carbon compounds that could form deposits. Water injection also prevents excessive temperatures in areas such as exhaust valves or pistons. High temperatures promote oil coking by causing oil to burn and degrade more quickly. This cleaning effect is both preventative and can help break down existing deposits.

EASY INSTALLATION

To ensure a hassle-free installation, all necessary connectors are included with the system. The detailed installation manual in English, with many illustrations and a clear layout, guides you step by step through the setup process.
