I have a 1986 300E. When I bought it, the hose which feeds the filter box was badly mangled. I finally got around to replacing it and I notice that the new hose has a slot in it to put an air temp or flow sensor into. The problem is, I can find no wires or connectors which would plug into this slot. Did the 1986 300E have one of these sensors? I suppose it's possible that I was sold an intake hose which was meant for a later model with the sensor.
