FYI... BMW uses different sized venturi's or jets in the
CDV tube/part. So while different cars can have a different sized jet or venturi... they all are basically a CDV. The part numbers can be different too.
Even my buddies old e36 M3 had a (metal)
CDV part/restrictor on the clutch hydraulic line. He took his out too.
And YES,
RealOEM.com can be wrong sometimes... but for teh most part it is a good data base - created by BMW themselves. So it makes it a decent research tool.
