Anyone know what these Manifolds are from?

[OBs]

I bought them some time ago, they are from a BMW but am unable to to find out which model they are for, I have tried Google and Realoem but have had no joy.

Part number's: 11621318211 / 11621318210

Stamped with BMW and made by Bischoff

Thank you

E34 M5??

This is what I was lead to believe Si, but have been informed they are not... I checked on Realoem and the picture is totally different.

It was the air pipes near the gasket faces that made me think that...

Correct! The realOEM/ETK picture is just to identify an exhaust manifold - it could show a cast iron one.

slightly O/T, what are those air pipes for, crankcase venting?

The pics on my OEM look fairly close Andy........ But those part numbers dont seem to exist E34 M5 part numbers are close ...........

They are connected to an air pump and it's to reduce the emissions by mixing air with the exhaust gasses to create carbon dioxide and water instead of carbon monoxide.

I've got a pic of an S38 manifold set-up in front of me from a 3.6 M5 and there's not much difference. The caption reads that the 3.8 version is very similar to this, so i would say it's from the 3.8 version..

Thanks for the replies guys... Oh and Ben

Thank you, I have just browsed through a few pages and I think your right, probably the 3.8 verson...
