Ams Performance Alpha Heat Exchanger Upgrade For Mercedes-Benz E63 AMG W212

Description: The Mercedes-Benz M157 5.5L BiTurbo engine does not use the typical intercooler you may be familiar with. Like many modern turbocharged European vehicles, this V-8 twin turbo engine uses coolant to lower the intake air charge temperatures through an air-to-water heat exchanger. While this method works well, it can quickly become heat-soaked robbing your engine of horsepower. Although adequate under normal driving conditions, the stock heat exchanger system (responsible for cooling boosted air) underperforms when your E63 or CLS63 is driven aggressively, in warmer climates or when subjected to extended periods of operation. An upgrade to the factory auxiliary heat exchanger in both overall size and efficiency, ours offers better cooling of the intercooler system fluid. Being 38% larger than stock, our heat exchanger core provides additional liquid capacity for greater heat dissipation. This allows the system to maintain lower fluid temperatures throughout extended periods o
