One of my two $26 Westach probes broke after maybe 30 hours and the
other seems to be on the way out.

Does anybody have experience with the Alcor probes sold by AirCraft
Spruce for $59? Will they last more than twice as long as the

Westachs?

Note: due to my muffler/exhaust design, the probes are located only

2.5"

from the engine.

the clamp-on type, they may not last due to movement/vibration. I have

EGT as high as 1600F.
