I will be converting to an alternative air cleaner soon, this cleaner and mount are a joke. I was reassembling the air cleaner after doing the turbo drain tube seals (which was a success thankfully!) I discovered that the seals on the 180-degree tube that goes from the air cleaner to the turbo are gone. I have ordered every possible combination of seals from the usual merchants and they are all only *one* size, the larger one that goes onto the air cleaner. Does anyone know the actual part number for the smaller seal that goes around the turbo inlet???
