Bouteille overlow l'expansion tête bouchon de réservoir 1j0121321b pour VW Golf MK4 passat audi
I just recieved the cap and tried it on my old Golf. The quality of the product is quite good, but apears to be lower then the orginal. It a pitty that the thread of this cap is a little smaller than the one on my car. Maybe this fits only with smaller engines.
good
