Our simple and efficient boost kit for the 200 and 230 Kompressor engines found in the earlier C, CLK, E and SLK models, provides an impressive increase in power and torque throughout the entire rev range of the motor. A new, larger diameter, lightweight crank pulley spins the Kompressor faster for increased boost. A slightly larger alternator pulley keeps the alternator spinning at factory speeds. The M111K boost kit comes complete with all required hardware for installation, no ECU tuning is required.
