PART NUMBER: 61-2817
This is for a factory all-metal Mazda thermostat and gasket for 1990-2005 Miata. The most reliable thermostat for the Miata!
Note this is actually the all-metal thermostat for NAs, but we list it here for both NA and NB because it fits all 1990-2005 Miatas and we use this thermostat in ALL of our NAs and NBs because we've found it to be more reliable than the NB thermostat which has a rubber component in it which deteriorates.
INCLUDES a factory thermostat gasket, which must be replaced when you replace the thermostat, and most places don't include it with the thermostat.
