I just checked Eurospares parts diagrams and you're absolutely right. They are the same part number for the inlet filter on both the 360/430.
When I picked up the high pressure filter for the 360 at an independent shop here locally, I had a good chat with the Ferrari master tech/owner who happens to be a good friend (oddly enough he used to work at the same Ferrari dealer I did, but many many years later on!).
Anyhow, he mentioned the same high pressure filter is in the 360/430. There is also a high pressure filter in the 575/599/612 apparently too as well. I personally haven't ever replaced one on any of those models, because most owners hardly drove the vehicles or put miles on them! Also I didn't even know it was there as the parts diagrams don't even list it (aside from the 360). So take that with a grain of salt about the later models until someone can get in there and physically confirm it.
I trust my friend, but i didn't ask if the part number from the 360 was the same one used beyond the 430 into the 575/599/612. It would make sense that it COULD be, simply because it looks like on the parts diagram for those that the same style fitting from the solenoid block is used to adapt into the high pressure line, but that could also be coincidence.
