bkhondaparts.com shows the prices to be the same for these
two parts. I have had this happen before with other parts.
The online OEM dealers always tell me they are the same
part; no difference. I do not know why this duplication
occurs. I asked once and there was no explanation, other
than IIRC something about Honda changes its part numbers
from time to time as some sort of adaptation to new models
that come out. I guess it is possible the source
manufacturer changed, too. Maybe it is a way to optimize
inventorying. This point comes up often at honda-tech.com
and no one bats an eyelash.
