Probe CHT Bayonet Adapter, Insight

Allows you to avoid using a gasket probe on the cylinder your CHT gauge monitors. For bayonet type probes.

Four types of CHT probes are available from Insight. While either type is satisfactory, the low profile style is more often used since it does not have to be disturbed when removing spark plugs. Engines equipped with electrical cylinder head heaters must use the gasket type probe.
