This adapter flange allows you to easily measure your engine’s oil temperature at the ideal location in the sump. Designed in house at MSW and produced locally to meet the need for an easy plug-n-play solution.
Most BMWs of the E36 and E46 generation read oil temp from the oil filter housing and on the earlier cars (including some E46s) this isn’t available over a CANbus.
The flange uses an OEM o-ring to seal against the bottom of the pan. The flange is tapped for 1/8-27 NPT threads, the most commonly used for aftermarket temp sensor.
Notes: Since this flange replaces the stock oil level sensor, you will get a low oil level light if using the stock dash. This part is intended for use on race and track cars.
Applications: M50, M52, M52TU, M54, M62, S62, S14, S54, and S50 EUR.
Installing the sensor into the flange requires a custom socket, but this easily done by purchasing an inexpensive deepwell socket and grinding flats on the side to use a wrench on it. The AiM sensors typically use a 13mm socket.
You can then use it to thread in your sensor. These are pipe (tapered) threads and require a sealant/teflon tape. We recommend Loctite 592.
To install the flange, drain your engine oil. Gain access to the bottom of the oil pan by removing any underpanels. Remove the stock oil level sensor and replace with the MSW flange. Torque nuts to 89 in-lbs. Route your sensor wires away from any moving or hot parts. Refill your oil.
