Why Replacement Matters: 
With age, thermostats can fail by sticking open or closed.

•  If stuck open: the engine runs too cool, causing poor fuel economy and increased wear.
•  If stuck closed: coolant circulation stops, leading to overheating and possible severe engine damage.

Replacing with a genuine Porsche thermostat restores precise cooling management, protects your engine, and maintains optimal performance.

What This Product Does
•   Stabilizes engine rotation and transmits power to the transmission.
