▲Features:
This products is a replacement for the plastic fitting on BMW PN 11537541992 and 11537544638. It fits the N54, N53 and N52 3.0-litre motors. This BMW PN consists of a 25mm (1.0") hose and a plastic fitting. This hose runs from the coolant thermostat housing to the front of the head.
This fitting is a direct replacement for the stock plastic fitting with no modification to any part of the system necessary. Simply remove the end of the hose from the plastic fitting and then the fitting from the head (hose does not need to be removed from the thermostat housing to do this). Then install the replacement fitting to the head and slide the hose and hose clamp over the fitting.
If you track or race your 335i then this is a highly advisable upgrade as this coolant fitting will not crack under high-temperature track conditions.
