AMS PERFORMANCE MERCEDES-BENZ M157 / M278 / M133 AUXILIARY HEAT EXCHANGER UPGRADE

From the factory, you can expect your Mercedes-Benz M157 / M278 / M133 engine to produce a high level of boost pressure (27.5psi as tested). This in turn, creates extremely high charged air temperatures prior to entering the stock liquid cooled heat exchanger (intercooler). Although adequate under normal driving conditions, the stock heat exchanger responsible for cooling this boosted air underperforms when your MB is driven aggressively, in warmer climates or when subjected to extended operation.
