BMW Differential Drain Plug – 1/8 NPT – M22x1.5mm

Easily add a differential temperature sensor by simply replacing your drain plug rather than welding a bung onto the cast aluminum cover.

These are useful If you are looking to log your differential oil temperature or to automatically turn a differential cooler on based on the temperature.

• External Threads: M22x1.5mm (Fits most BMW models)
• Internal Threads: 1/8″ NPT

Notes:

 – Includes a new OE-BMW sealing washing.

 – We currently do not plan on making any more of these once they sell out.
