JPI CHT Probe Gaskets 14mm/18mm. FAA TSO-C43/AS8005. The Cylinder Head Temperature (CHT) - Gasket Type (Washer) - probe, replaces the standard copper sparkplug gasket on the sparkplug. You may install the probe on the upper or lower spark plug (the one that provides the best correlation with the other temperature probe). Due to the sparkplug location, the gasket probe may read 25'F higher (generally the sparkplug is the hottest part of the cylinder, which will cause this discrepancy). |

This product is great, and was a direct fit with quick installation. Works great.
Went on and worked as described. A little costly
Installation depends on using a 12 point deep socket. Otherwise not enough room between the wiring flange on the gasket and the cylinder spark plug wall to get a good grip on the plug. Way over priced.

Thank you for providing this follow up, we will post it on our site for other customers reference.
This depends on your engine, not the JPI unit. If your engine requires 14mm you will need those, vice versa for 18mm.
It is the thread diameter of the spark plug this would be installed under, an io-550 would use 18mm plugs.
