This cap is for the expansion tank of the Porsche 924S/944 and 968 cooling water circuits, in used condition. The cap of the coolant expansion tank protects the system from overpressure and should be replaced after the years. You can also find a new cooling water reservoir in our store.
The cap is an original from Hella/Behr. Behr was also the original equipment manufacturer for the cap and accordingly supplies the best possible quality.
