Aluminum Water Hose Fitting Replacement for BMW 1 3 5 6 7 Z4 (Engine N52 N53 N54 and N51 3.0-litre),Replace for 11537541992 11537544638

Great Mickey Mouse Flange!If you work on BMW then You know the oem flange is crap and disintegrates over time. This aluminum one is a huge upgrade and fits excellent in the Oil filter housing. For the price it is cheaper and more durable than an Oem which is a great value. I have had it installed on an e90 for 6 months not with zero leaks. Functions flawlessly !

Two weeks later, works GREAT on my 2007 BMW 328i Convertible E93. Great upgrade to DESIGNED TO FAIL BMW plastic connector.

If you have a BMW with this type of coolant flange, it is a must replace item and will last forever and wont leave ypu stranded. If your plastic flange is in pieces when you remove it make sure to clean out and account for all of the broken pieces. Very easy to install. The one I received didn't fit properly due to the supplied o ring which seemed like it was thicker on one side, I replaced it with an o ring that I had and it works perfectly.

First, E90 was listed for the 335i but not the 328i. It did fit the 328i as you can see in the pictures. However, irregardless of which engine, the adapter should have fit.When I first tried to install it, it was forcing the bolts at a slight angle where they still grabbed the threads but would have stripped out. I redrilled the hole with a 5/16 bit. The initial tolerance was just way too tight. I was then able to test fit the adapter without the oring and everything sat flush. I installed the provided oring and used synthetic grease, the adapter popped in with very little fuss.Make sure not to tighten the first bolt all the way so you can move it clockwise or counter clockwise ever so slightly to get the other bolt started. I was able to finger tighten both of mine.To remove the old plastic piece, I cut a V shape with my dikes and was able to break it out without cutting or damaging the hose. After that I was able to slide off the compression ring. The provided clamp does suck, but very usable.Be very careful and hold the hose downward so the stuff falls out and not down into your water pump. If you accidentally drop plastic down the hose, remove the two hoses from the reservoir and use your garden hose to push it out the bottom reservoir hose.I did read the negative reviews but a lot of people try and fit orings dry or with the wrong lube.

This part came I was super happy, looked Good felt good. I have 335xi n54, the morning supplied was huge. Wasn't a big deal, I had other to replace it. After fixing that issue I realized the shape was off slightly. I couldn't even get my bolts to thread in. I then had to drill out the hole multiple times to even get the bolts lined up, it was so far off there is barely any meat left on the ears where the holes are. If I didn't absolutely need it, I would've sent it back.

Fit perfect better than dealer

Good quality but item arrived 6 days late. Had to purchase another one locally. Will keep for future use.

Works amazing definitely must have upgrade over the plastic one
