Intercooler for Mercedes Benz Maybach S-Class S560 S650 (2018-2022) 4.0L 6.0L

High-Efficiency All-Aluminum Intercooler for 2018-2022 Mercedes Benz Maybach S-Class (X222/Z223)

What it Does: The all-aluminum performance intercooler replaces the factory charge-air heat exchanger on the 2018-2022 Maybach S-Class to reduce intake air temperatures, prevent heat soak, and sustain peak twin-turbo boost delivery.

The Stock Mercedes Benz Maybach S-Class Heat Soak and Crimp Failure

The factory low-temperature charge-air radiator in the X222 and Z223 chassis relies on standard tube-and-fin cores paired with composite plastic tanks clamped by crimped aluminum gaskets. Under repeated high-load cycles, the twin-turbocharged M176 4.0L V8 and massive M279 6.0L V12 generate extreme thermal energy. Over time, engine bay heat cycling causes these plastic end tanks to embrittle and the mechanical crimp seals to weep coolant. Furthermore, the stock core's fin density creates airflow restriction and succumbs quickly to heat soak, leading the factory Bosch MED17/ME17 ECU to pull ignition timing and dump boost to mitigate knock.

The Engineering Solution

Engineered as a robust cooling upgrade, this replacement charge-air cooler features a high-density, 1-row crossflow aluminum tube-and-fin core welded directly to structural all-aluminum end tanks. By eliminating crimped plastic junctions, it prevents pressurized coolant leaks under elevated charge temperatures. The optimized internal flow passages reduce hydraulic restriction across the low-temperature auxiliary cooling loop, providing faster thermal recovery and lower post-intercooler intake manifold temperatures. Precision CNC-machined inlet and outlet ports match original equipment routing for a leak-free, drop-in replacement that retains factory brackets and plumbing without throwing diagnostic trouble codes.

Frequently Asked Questions & Fitment Warnings

Does this fit the X222 and Z223 Maybach S-Class?

Yes, this is a direct fit for the 2018-2022 Mercedes Benz Maybach S-Class equipped with the M176 4.0L V8 and M279 6.0L V12 engines. Note: This unit is engineered solely for charge-air low-temperature cooling loops; it does not contain integrated engine oil or transmission oil cooling circuits.

Do I need to vacuum bleed the secondary cooling system after installing this intercooler?

Yes, modern Mercedes-Benz water-to-air charge cooling systems require vacuum filling and proper electronic bleed cycling to eliminate air pockets and guarantee optimal thermal transfer.

The Mercedes Benz Precision Standard

Engineered to satisfy demanding European automotive standards, this aluminum charge-air cooler maintains strict factory clearances to prevent parasitic heat soak, ensure fault-free operation, and preserve smooth, factory-grade twin-turbo power delivery without triggering engine check lights.
