I didn't find the invoice from the dealer to verify, but I ordered
this part from the dealer twice and
received one only half as long as the original part. The parts guys
were perplexed as well when
I showed them the original part and where it went, but could only
offer, "buy two". They were
about $20 each so I rejected that idea. The part # appears correct
and shows to be 1360mm long.
The importance of a good seal cannot be over-emphasized. Any part
without a perfect seal will
leak into the cabin since the opening is at the bottom of the plenum.
The foam seal is impregnated
with a tar-like sealant that provides the proper water-tight seal when
compressed. Ordinary foam
seal will not provide the watertight seal necessary.
