Question Defi EGT probe thread size?
Does anyone know the size hole I need to tap into my exhaust for the Defi EGT boss?

As per the picture below.

The thread is much tighter packed than a normal M10 for example.

Thanks

Nathan..

"normal" thread pitch for Subaru bolts, and Japanese cars in general, is "fine" which is 1.25

You should need M10 X 1.25 but any localbolt supplier will be able to tell you what you need to know!
