The Forge PolarCooler Chargecooler radiator is specifically designed to enhance your vehicles auxiliary cooling system and help overcome the performance loss and efficiency issues associated with higher temperatures, created from aftermarket ECU tuning and high-performance demands on your engine.Motorsport raw alloy or satin black powder-coated finish*Triple pass water flow core gives greater cooling efficiencyCNC machined couplerslarger 23-litre coolant capacity compared to the 8.3-litre OE coolerBuilt-in bleed pointA Charge Cooler works on a very similar basis to an uprated intercooler but uses water instead of air to provide additional cooling a key component to this system is the cooling radiator. The PolarCooler upgrade radiator core size is increased over the OE system which speeds up heat transfer and increases cooling characteristics which should, in turn, lead to lower overall operating temperatures and a quicker reduction in temperatures once the system is hot.The Forge Polar
