Removal Kit For BMW Diesel Engines Adaptor Cooler Thermostat Bungs E46 E39 M47 M57 M67

The BMW E46 E39 Adaptor Cooler Thermostat Bungs Removal Kit is a diesel-focused retrofit designed to simplify cooling and intake maintenance on a broad range of BMW engines. Built for diesel powerplants within the M47/M57/M67 family, this kit supports straightforward removal of thermostat bungs and smooth integration with the adaptor cooler, helping your engine breathe more freely and maintain efficient combustion. Compatible with engine codes M47, M47N, M47N2, M57, M67, and M47R (OE part number 391240), it’s tailored for diesel BMWs and ready to install with minimal downtime. Note: For diesel vehicles only, not for gasoline vehicles.

Key benefits include easier maintenance, improved airflow, and enhanced overall performance. The kit uses a high-quality aluminum alloy for durability and reliability in challenging engine bays, and it’s designed to eliminate internal restrictions found in older hoses. This translates to more consistent throttle response, reduced exhaust smoke, and better fuel efficiency over time. All electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.
