The term your looking for is "stud".

Apply PB blaster, tap lightly with a hammer, wait half
an hour, put on some more pb blaster, tap again, then
use some vice grips to turn it out.

Studs are good for this. If they weld themselves to the manifold or
whatever they are screwed into, it's a good thing. You can put some
anti-seize or thread locker on them first, but it will burn off and the stud
will rust in place eventually.

Lots of penetrant, judious heat, tap tap, more penetrant, repeat over
several days. Get a brand new Vice Grip (by brand, no import junk!) and
give it a go. I've had one come out with a major screech on the second
day of swearing at it. Good luck.

Replace with a suitable stud from dealer or NAPA. It would be a good
idea to run a suitable tap into the hole to clean out the crud first. I
expect it will be a 3/8"-16 NC thread.
