JPI EDM Option CHT Gasket 14mm

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).
