Thanks for the words of wisdom. I will just hook up the one probe in the downpipe for now and later when I get somemore doe I'll get the rest tig'd to the manifold.

Later.

You can just drill a hole in the manifold and then tap it with the same thread as the sensor... That would be pretty secure and simple.

Easier said than done; the thread pattern is lik 1/32's.

Don't they use the 1/8" npt? That is kind of standard. Check out omega.com for some thermocouple supplies.
