TCI Products **NO LONGER AVAILABLE** Replacement Thermostat Honda ST1300 (2003-09)

This is not a factory Honda part, this aftermarket thermostat replaces the factory Honda part exactly and is calibrated to the same temperature. The O-ring that is included is for use on the thermostat housing. Upon removal of the O.E.M. O-ring you will notice that it has a bigger cross section diameter than the one that is included with this thermostat. This is because the O.E.M. O-ring tends to swell over time. If you were to go to Honda and purchase this O-ring it would have the exact same cross section diameter as the one included here.
