I will soon be buying an EGT guage and was wondering about the two different types of temp probes out there. The thermo-couple and the tap-n-screw. The Westach EGT comes with the thermo couple and is relatively cheap (also temp goes to 1700). I was wondering with the thermo-couple design, isnt there a possibility for leaking exhaust? Which wouldnt be good. Plus it probly looks kinda ****ty. If anyone has any experience with the thermo-couple, i would like to hear from you. Also, if anyone wants to tell me to just get the Autometer guage, that is fine too.
