Brass plug exhaust manifold?

[SeaGriff]

I have a freshly drilled and tapped hole in an ATS Pulse manifold. I need to use a 1/4" NPT plug until I install the probe. Can I use brass?

Are you sure there is not one in the box? When I got mine it had one floating around in the box.

A brass plug will work just fine.

Yes. I had the same concern. I calculated the pressure the brass plug will stand and it is fine. Can't find my calc's now. I used one for several thousand miles w/o problem.

Brass may work but your much better off with steel which is available at your local plumbing suply house,exhaust manifolds get really hot. I just bought a 1/8 npt plug for my 6. 7 when i got rid of it.
