You don't want any hot air going into that intake, so sounds like a win although like you said, in reality wouldn't have made any difference at all by the sounds of it. Hot air = less combustion...Hence why people put on 'cold air intakes'. We have one from stock...so all good  |
I will pop the plug in. Phil did say that the part was the oem replacement for an M103.098. It had the identical part number as the old and came with the MB part sticker on it. Your explanation of the temp sensor makes sense, but would also seem to indicate forward enginnering in parts, if it wasn't available on the M103 to begin with.
Anyway, with the new air hose in place, the operating temperature dropped significantly. The old hose was really shot! At operating temps and speed here, now, the coolant temp hangs right at the top of the 8 at 80c. It approaches the 100c level when in stop & go or stopped. Only once went above 100c, when the water pump went last Christmas Eve!
