Eaton M45 Supercharger + Tuning Pulley - Mercedes-Benz A1110900980 / A1110901080

Professionally remanufactured Eaton M45 supercharger equipped with a smaller performance pulley and a matching 6PK1330 multi-ribbed belt. The kit is designed for Mercedes-Benz vehicles with M111 Kompressor engines.

The smaller pulley increases the supercharger's rotational speed, providing faster response and higher efficiency of the forced induction system. In our tested configuration, we achieved a power increase of approximately 30 HP, confirmed by dyno testing, without the need for ECU tuning.

RECOMMENDATIONS

We recommend this modification for vehicles that are in good technical condition and maintain correct factory performance values. Before installation, please check the condition of the intake system, belt drive, idler pulleys, tensioner, and other components working with the supercharger.

IMPORTANT

Before purchasing, please compare the OE number on your old supercharger. If you have any doubts, feel free to send us your VIN, the OE number, or a photo of the supercharger nameplate — we will help confirm compatibility.
