What the heck is this thing?

[dondmar]

I got this attached to a Weber single 40 DCOE setup I bought a while back and never got around to figuring out exactly what it was for. It was bolted to the intake side of the carb and I guess is either some type of velocity stack or just a way to turn the air cleaner horizontal for space issues. I has "BMW AUTOSPORT" stamped on it but no roundel so I'm not sure if it's a BMW accessory or aftermarket. I want to sell it (need bodywork money for the project) but I have no idea what it's worth and what to ask for. Let me know what you guys know! Thanks!

Looks like it may be an air cleaner adapter.

maybe it fell off one of these cars ??

It actually says B N W Autosport.

Looks like the one that came off the Weber 40 that I sold to Doug... It's an air filter adapter.

Looking at the casting with the smaller hole on one of them, I'd guess these are 90 degree intake manifolds to use dual down-draft Webers (DCNF maybe?) on an in-line engine.

To me, the castings look too beefy to be just air cleaner adaptors.

I agree, It's an air cleaner adapter for side drafts.

I have a similar but slightly different set
