BMW S54 Engine Electric Water Pump Conversion Plate E46 M3
This plate allows you to convert from the stock S54 water pump to an external electric water pump. This plate deletes the thermostat and the water pump and creates a port using an AN-16 O-Ring boss. This means you can use a variety of different connections at the front of this place using AN-16 to hose barb, wiggins, or AN adapters. We also have an extrusion at the top of the plate for a bolt to attach for engine removal and installation. The second smaller port is an air bleed hole which can either be used to bleed the water system or plugged depending on your application.
