I would like to install an EGT gauge on my 2.0. From what I've read, it seems most probes go within 6 inches of the exhaust valves on the header. I don't want to tap a hole in my stainless heat exchagers. My thoughts were to put the probe on the exhaust tubing that connects to the heat exchangers. I realize the exhaust is most likely cooler at that point, but should work OK??

Do they make an EGT probe that is a clamp on type so I could connect it closer to the heads?

anywhere but where they tell you to install it is inaccurate

its just a hole and a tap. worst case you have it welded up if you dont like it.

To get an accurate reading you need to be within the 6" range from the valve.
If you put it further down the exhaust will be cooler than up near the exhaust port.

I know...it's just the thought of drilling a hole in a perfect set of stainless exchangers is killing me.


That's what the gauge advertisements seem to be pointing towards.

I guess that means there is no EGT probe/sensor that just clamps on to an exhaust tube?

Drill the hole. It's really not that big of a deal for a competent shop to repair/weld. Don't worry about it.

I put mine a max of 3" from the valve...

every inch makes a difference!

Six inches from head is what I recall.

Just drill the tiny hole and be done with it!

The info those gages provide is priceless.

Thanks for all the advice...I'm getting my out, no I mean my drill!
Thanks again
