Is the vaf different in a SOHC?
 

Back when I first bought my Pro I found the airbox was broken. I bought one cheap on eBay and it came with a vaf. I only needed the bottom piece, so I still used my original vaf. But as I was looking at them I noticed the part numbers were different. The one on my DOHC is BP05 13 210, with a number under it 197100-4110. The one on the eBay vaf (which I think was from a SOHC) is B6S7 13 210A, 197100-4090. Are these different models of vaf, or are they just meaningless numbers? I wanted to give one of these to my buddy who has a '91 DX and wanted to give him the correct one (if there is such a thing) - he's kinda become my hand-me-down brother! :D

They appear to be identical. It's probably a case of a superceded part number, since yours is a '94, the one you got is likely from an older car.

Although, the one from eBay may be from a 323 and not a Protege.

it actually sounds like it came off a 323, lol
