The only problem is that different probes use different hole sizes.
Could be a problem if your current ones are larger.

Bob;

Thanks for lead.  It's interesting that they are guaranteed; but I'
concerned that the SS housing may not last long 2" from the port in a
rotary.  The ones I've been using are inconel 600 which I think is a better
bet.  Also since my wiring assumes the 4' leads, I better stick with the
same kind I've got.

Happy New Year!!

Hi Al,

It's always easiest to replace what's there, and the price difference
isn't that great anyway.  I used the P-110 probes described at:
http://www.aircraftspruce.com/catalog/inpages/eip110egttit.php because
I didn't know about the Micro-1000 probes at the time.  I haven't heard
of any problems with the probes because of the rotary exhaust.  Any of
them should handle the temperature OK if the pulses don't get them.
