Activates cooling fan at 80°C instead of the stock 93°C. Requires use of Mugen low-temp thermostat.

Compatible with all B/D/F/K-series engines.

A low-temp thermostat is highly suggested to be used in conjunction with this sensor.

F & H-series note:
This fan switch is also compatible with USDM H-series engines that use 2 fan switch sensors (A + B). For USDM 92-96 H-series (and 94-97 Accord F-series engines), this sensor replaces the OEM fan switch "B" on the cylinder head upper water neck. Must use Mugen H-series fan switch "A" located on t-stat housing to complete low-temp sensor upgrade. A low-temp thermostat is highly suggested as well so that all sensors and t-stat are working at the same low-temperature operations.
