This Porsche Coolant Temperature Sensor (OEM 99660640501) is a genuine used part sourced from a donor vehicle. It monitors engine coolant temperature for the ECU on 2.5L, 3.4L, and 3.6L H6 engines found in the 911 and Boxster. When it fails, you may see rough idle, hard starting, or poor fuel economy due to incorrect temperature readings.
