Airbox. Different types between models?

Curious
Are there any differences between the airbox designs used on the different models?

The seller has failed to mention the locating peg on the lower air filter case has broken off and is missing :sad:

The 47x airbox (top) has a groove for a o ring but the 1ge (bottom) has no o ring and just uses a seal.

Wrote to the seller to ask if they new
No idea - but Yamaha went to the trouble of marking them either 47X, 51X & 1GE & the numbers are moulded in - so I assume there’s a difference, as there are plenty of other parts stamped 47X on 51X that they didn’t go to the same trouble with. 1GE & 47X are not restricted in anyway - hence they’re “full power”. I’d guess the volume & flow is different in some way - to match the restricted exhausts & give the correct pressure - but I’m just guessing. I doubt there’s much difference.

Never seen a airbox with 51X moulded in but the part numbers are different for the RZV500

Maybe the size and diameter of the snorkels between main and side airbox are a different size or the part number change is just because the RZV500 doesn't
have the foam pads on?
