While there are counterfeit filters in the world, the initial thread that was referenced, and the source of this conspiracy theory, showed a comparison of a D01 and a D02 filter, alleging the D02 was a fake. Part numbers are shown in the picture.
FALSE ASSUMPTION, FALSE INFORMATION
The stamping on the filter plate (6 or H or whatever) is simply a reference mark for the manufacturer, likely indicating batch code. This helps if there is a defect and the part needs to be
The video from the same thread, made by an independent dealer. highlighted 5 differences on the D01 filters, all inconclusive except #2, the lack of oil pressure relief valve inside.
If oil is too cold (thick), it will open the oil pressure rlief valve, and the oil will not be filtered. You should know that not all oil is fed through the filter anyway, Without the valve, all oil is filtered, which may force the thick oil through the paper and possibly tear the paper. So definitely look for that. Genuine Honda parts have part numbers on them, or on the original packaging.
Anyway, there is no information I've seen in this thread that anyone has bought a counterfeit filter from a dealer or from Revzilla (and it's Honda dealership). I would recommend buying from a Honda dealer.
