The adapter works as advertised and allowed an aftermarket probe to go into the stock location that had a different thread diameter. I was installing an Edge CTS3 monitor and needed to add their probe kit. The issue I ran into is that the Edge probe starts out narrow and then widens and the probe tip would not even stick out the bottom of the adapter after being tightened. I had to drill out the inside core of the adapter to allow the probe to go in farther to get into the exhaust chamber. Not sure what other 3rd party probes are shaped like, but this is what I ran into with the Edge EGT probe.
