Oil temperature sensor thread size

dts3 · 11-05-2018, 02:10 AM

I wanted to install my Defi gauges over the weekend but I ran into a problem. My original idea was to use 1/8 bspt tees for both the stock oil pressure and stock oil temperature. The pressure sensor (that everyone uses in their DIYs) is 1/8 bspt. The temperature probe is quite a bit larger... The end result is that I could only use one of my tees, and my Defi temperature sensor isn't installed. I'm adding side by side pics of the OEM & Defi pressure sensors and the OEM & Defi temperature sensors. Does anyone know what size these threads are?

Based on posts by the GTR guys, I suspect the thread size of the stock oil temperature sensor is M12 x 1.25.
