MUCH better than the cheap plastic OEM part, Just a reminder though, these thread into an aluminum block so be very careful to start them finger tight first, then evenly tighten both bolts to push the fitting into the chamber. If you don't, it will slightly misalign and you run the risk of stripping the threads. The one comes with the replacement o ring, and be sure to get some antifreeze on that seal prior to attempting to push it into the chamber. IT IS A TIGHT FIT, but that's what you want, so just be careful. You might also want an extra hose clamp on hand, as the one that came with this began to bend as it got tight, so I had to replace it for peace of mind. Overall, great product though.

Snapped bolt

I tried putting it on my n55 from a m235i and it did not fit properly. I was in a rush to try to put it on and thought it was on properly and I thought it did. And I snapped the bolt because the bolt because it was not aligned after I looked at harder I do not recommend for a n55. do not get this cheaply made pos. I recommend getting it from fcp euro where parts will actually fit and not fail.

May not fit correctly or is difficult to fit on.

Would not advise buying. It wouldn’t fit with the o ring nor with the old one, it would only go in with no o ring. So I had to put back my old hinge and o ring. Edit: I had to add coolant to the O ring, along with somewhat forcing/prying it in in order to get it to fit flush.
