Same threads as a spark plug. The easy repair is a plug rethread kit. It
has an oversized insert with a self guiding fluted cutter/tap
combination. Then you trim the threads on an insert so they don't block
the sensor tip. Screw it into place and screw in the sensor. About the
third time you drive the car that insert will become a permanent part of
the manifold.

Very common repair, done all the time.
