In keeping with the performance of G55 AMG Kompressor, we decided to offer a custom engine oil cooler to help in cooling the heat generated from the V8 AMG power plant. We decided to come up with an oil cooler that will fit the stock location and maintaining all the factory connections. Our custom cooler is 50% thicker than factory, going from 1.5 inch thick to 2.25 inch thick. This is the thickest core that we can fit on to the factory bracket and front under panel enclosure while maintaining the factory original fittings connection. Truly a bolt-on engine oil cooler for the 2004 - 2012 Mercedes W463 G55 AMG. The upgraded engine oil cooler will keep your V8 AMG running cool when you need it. 100% made in the USA !
