With modern day aftermarket ECU tuning pushing powerful engines harder, in certain conditions the vehicle will run the risk of receiving inadequately cooled air affecting the engines efficiency and ultimately losing power. With this in mind, Forge are proud to release the PolarCooler to enhance the auxiliary cooling systems on the BMW M3/M4 vehicles

Building on lessons learned in developing our successful range of Audi and Mercedes chargecooler system upgrades, we have now designed this uprated chargecooler radiator for the BMW M3/M4. 

Available as a single item or for the ultimate cooling package to be use in conjunction with our Chargecooler and expansion tank kit - FMCC1

Offering a significant increase in core surface area and volume (545x460x32mm)
