Reviews
According to alcor, these are the correct probes for my M20TN acclaim with TSIO550-G1. They work and install as OEM, but the clamp has to be trimmed to size and deburred. TCM M-0 required that they be safety wired, see AC43-13 for best practice.

My CHT was not registering. Changed out the probe for this one and worked great. All the parts including the heat shield and zip ties came with it.

Type j and type k thermocouple leads are two different alloys that react with one another based on the thermocouple effect. Each egt/cht gauge requires a certain thermocouple type to respond properly.
