We have to understand first that there are usually 3 types of parts:
1- Original OEM parts that are approved by the Vehicle manufacturer. (large volume parts usually have more than one approved supplier because imagine if a supplier has a fire in the factory, or any other problem that interrupts production, and also to create a price competition avoiding being dependent on just one.
2- Parts from reputable suppliers that will use their own brand, but are not endorsed by the manufacturer, therefore they are found in parts stores and not as an OEM in dealerships authorized by the vehicle manufacturer.
3- Counterfeit parts, which try to pass as original OEM parts, but are fake.
I was a supplier for NGK do Brazil for 25 years, which were suppliers of OEM parts for manufacturers such as Honda motorcycles, Yamaha motorcycles, Volkswagen, GM, and others (so I will only comment on type 1, OEM).
When I was asked to manufacture a new OEM product, I often had access to the assembler's drawing and specifications, plus NGK's more accurate drawing and specifications (because they would be responsible for the part and had more expertise on the subject and with a laboratory and superior durability testing to avoid future problems).
I made my design and specifications internally with greater accuracy to be able to manufacture the molds and tooling needed in the manufacture of parts, so that any normal deviation in large-scale production would never be greater than what NGK admits.
So if an NGK competitor such as BOSCH was also an approved OEM supplier, the manufacturer's features and specifications would be on the part, but not necessarily NGK features and not mine either, which can result in a slightly different appearance.
In this case of the filters, maybe the color of the inner paper can be different, but still meet the OEM specifications and be approved by Honda.
