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.

Get The Most Power From Your M157 / M278 / M133 Equipped Mercedes-Benz

Whether you are running stock or upgraded components on your Mercedes-Benz turbocharged engine, the Alpha Performance Mercedes-Benz M157 / M278 / M133 Heat Exchanger Upgrade offers much greater efficiency – providing consistently cooler boost temperatures while combating heat soak issues.  Beneficial throughout everyday driving, this level of cooling is even more crucial to consistent performance on a road course or dragstrip.

An upgrade to the factory 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 of high throttle operation. To improve flow and reduce pressure drop, our engineering team went a step further by tapering the inlet and outlet for smoother flow.  All of this will result in cooler intake air charges and maximum power!

Super Easy, Direct Bolt-In Intercooler Upgrade

With normal hand tools, the Heat Exchanger Upgrade installs within 1.5 hours.  Simply remove the wheel, inner fender liner and the factory heat exchanger.  The new unit swaps right in using factory hardware without any cutting or modifications to your car.
