Product Features:
This product is made from high strength aerospace aluminum.
Also, this product was designed to maximize the resistance to breakage, so that it will not fail.
The coolant flow path through the center of the fitting is optimized to maximize coolant flow.
There are no sharp corners on this fitting so that the coolant will not be disrupted as it passes through.
This product is a direct replacement for the plastic fitting on BMW PN 11537541992 and 11537544638.
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.
The plastic fitting on this hose is a known weak spot in the coolant system as it commonly cracks and leaks.

The worst case scenario happened to me, I was out driving around and the plastic fitting decided I needed to call roadside assistance at 10pm.This new flange came in and it was a tight fit with the O ring. When I first tried to put it in, it wouldn’t go all the way in, but after I looked at everything, not all of the old fitting had been removed. There was still part of the fitting blocking the new fitting from sitting correctly. After fully removing the old fitting and cleaning things even more thoroughly, this installed in my N55 without any issues.

While this part may have fitted - I didn't end up using it as i felt it was below par in comparison to oem that came with the hose to the thermostate attached. The plastic felt a little sub par for an expensive engine and there was really nothing special about the clamp. I gave three stars because I felt it would work as described but also three stars because I would not have bought it if it had been offered to me in person at a shop when compared to the part I ended up purchasing that was produced to oem standards. I am sorry for the poor review but . . .
