With this in mind, Forge are proud to release another PolarCooler as the first auxiliary cooling system for the BMW B48 & B58. Following extensive testing on the road and dyno working with 3 different styles of water core with different fin pitch configurations, we are proud to present the ultimate in frontal water cooling solutions.

After considerable trials with different intercoolers cores, we have again opted for a core of bar and plate design, and along with an overall increase in dimensions we have been able to drastically improve the cooling ability when compared to the factory intercooler. In the construction, we use CNC machined bayonet couplers which allow an easy plug and play install. The intercooler is supplied with easy to follow instructions.
