ScienceofSpeed Radiator Sensor Adapter - S2000, 2006-09

Most aftermarket radiators for S2000 are made with the 2000-05 coolant temperature switch thread size. Some radiators, like Koyo, include adapters. For other brands, this adapter is CNC machined for a precision fit and allows the factory 2006-09 switch to thread into the larger 2000-05 switch threaded hole. Includes o-rings for adapter and sensor.
