The latest development from Snow Performance!
Complete kit with freely programmable 52mm OLED-gauge and optionally Dual Stage Technology.

*Fits to all turbocharged engines up to 3.5bar boost.

Optimal Cooling with Water Injection

Obtain up to 10-25% more power in your turbo- or supercharged engine, even if it´s pre-tuned, by using the Boost Cooler™-Water/Meth Injection System!

The main function of the Boost Cooler is to suppress detonation caused by high temperature and pressure developed within the combustion chamber when the effective compression ratio has been taken beyond the auto-ignition point by either a turbo or a supercharger. Water, with its high latent heat content, is extremely effective for controlling not only the onset of detonation but also the production of oxides of nitrogen in the modern leanburn engines.

Furthermore, the Boost Cooler doesn't create an intake restriction like an intercooler, and unlike race gas, it reduces intake air temps up to 60°C and improves charge air density too.

Snow Performance systems effectively steam clean the valves, valve seats, and even the piston tops and intake when they inject. This reduces carbon build up. The Boost Cooler™ can be installed in a matter of hours without having to remove bumpers or do custom intake piping.

More Power by Boost Cooler

With the Boost Cooler, you can achieve up to 10% extra power for suction engines. The optimal cooling compensates for power losses at higher outside temperatures. In addition, deposits in the combustion chamber and intake manifold are reduced.

116 Octane Race Gas Performance

For positive displacement superchargers (Eaton, Twin Screw) and small fast spooling turbos see (e.g. K03/K04 turbochargers) use the Boost Cooler Stage 2 MAF or our Stage 3 kits for best performance.

Dual Stage Technologie (DST)

The Stage 2 has the ability to progressively command 2 Hyper-Sonic? Nozzles independently of one another. This sophisticated dual stage injection management yields the highest increases in HP and cooling along all stages of the engine allowing you to greatly increase the boost & timing of your vehicle safely.

Stage 2 POWER-MAX Europe Edition

Die Europe-Edition (display & programming in BAR) is exclusively available only by Snow Performance Europe and its European authorized dealers.

52mm OLED Control Unit

The all new Snow Performance Stage 2 Boost Cooler water-meth injection system comes fully revamped for all turbodiesel vehicles as also trucks, marine applications and so on. It uses a progressive 52mm-gauge style controller that proportionally injects more or less according to boost pressure.

Start and full points are adjustable for engagement and delivery curve to match what the engine requires. Proportionally injecting according to boost pressure gives an accurate delivery of water-meth and allows cooling and performance improvements over a wide range for improved drivability.

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.

This is compatible with both Petrol and diesel cars

To ensure the part(s) you have ordered fits your vehicle, we run a compatibility check prior to dispatch. We can do this either using your registration number(UK) or the last 7 digits of your VIN. Simply enter your car details prior to checkout. 

The settings on OLED control unit can be made within a few seconds without any prior knowledge. The only thing you need to determine is at what boost pressure the injection is to begin and what the maximum boost pressure is. - The variable injection of the Boost Cooler is performed within these two preset boost pressure points. By using the optionally Dual Stage Technology, you´re able to set a 2nd nozzle mapping for optimized injection quantity especially at higher engine load states.
