The Mishimoto 60°C racing thermostat for 2002–2006 Acura RSX replaces the factory thermostat with a lower opening temperature unit to promote earlier coolant flow. Opening at 60°C versus the standard 78°C, it helps reduce and maintain cooler engine temperatures, which can be beneficial for modified or turbocharged applications. It is a direct-fit thermostat for 2002–2006 RSX models.
