NOS Mercedes AIR FLOW METER BOSCH NEW M103 W201 W124 W126 R107 A0000742014. Condition is New (NEW OLD STOCK) This part is brand new, never ever used, never mounted to a car/engine at all. I believe this item was originally packaged with the bottom rubber boot that goes to the intake manifold. But obviously never used, and that part has been since separated from this packaging. It had been sitting on a shelf for years, and I just don’t have any cars with an m103 any more. PLEASE CONFIRM ALL NUMBERS ARE CORRESPONDING AND CORRECT TO YOUR OWN PART NUMBERS! I would highly suggest getting the new potentiometer reset by a technician that know what they are doing. This can cause issues with your engine running poorly. There will be no returns on the item in the case of buyer error, HOWEVER, there will be returns accepted if, for whatever reason the part is faulty or not as described. The part will not be coming in a OEM box Thank you
