I was wondering what the EGT probe is. I saw an exhaust manifold for sale, that says it has the hole for it, but I'm not sure what it is. Thanks guys.

An exhaust gas temperature probe. It's a temperature reactive sensor that signals a connecting gauge of the corresponding temperature. In the case of your pre-tapped hole, or bung, in the exhaust manifold, that location would allow the placement of an EGT probe that would measure the temperature at that location (very prime).

For many, monitoring the exhaust temperature is an excellent method for monitoring the correct air fuel ratio in your engine. In the fragile balance of turbocharging, with all of the additional air it brings, knowing this temperature is of the utmost importance.

No, the O2 sensor measures air/fuel ratio.

AH! So you would hook it upto an Exhaust Temp gage? I'm a dumbass. What do the readings on it mean. Like if it was higher....it would mean what?

Here is mine. It would be to your benefit if you are going turbo to research this and any other info related.

Basically, the EGT gauge tell you 'how' hot you are running, while the A\F gauge tell you 'why' you are getting that hot.
