INTERCOOLER PUMP UPGRADE

RENNTECH's intercooler pump upgrade focuses on the Achilles' heel of forced-induction Maybach and Mercedes-Benz, with a pump that nearly doubles the capacity over stock. The larger pump, however, is just one part of a comprehensive tuning solution that adds a dedicated radiator to the car's intercooler package for consistent performance.

SUPERCHARGER PKG

With this package, RENNTECH delivers instant throttle response from idle to redline, 50% more power than stock, and vaults your Mercedes into supercar territory.
