Mercedes-AMG C63 Spool M177 Upgraded Heat Exchanger

The Spool upgraded heat exchanger for the Mercedes-AMG C63 and C63 S uses a competition racing core with much more volume than stock to cool the M177 water-to-air intercooler system.

Why you need it

More core volume means more thermal capacity, so coolant is colder before it reaches the intercooler and charge air temperatures stay lower. That keeps performance consistent under high load and repeated hard runs.
