Also, that assembly includes TWO sensors: The MAF (two wires inside small tube) and the Intake AirTemp sensor (bulb on outside of tube). If you are trying to build your own MAF sensor assembly, I applaud your initiative but I think it is more effort than it is worth. Rockauto sells off-brand sensors for like $50. Has to be better than a homebuilt.
