My 73' 240z has a grey/blue air cleaner that does not appear to have been repainted. Has anyone seen this before? I am wondering if may from a later model z. Even the stickers appear to be factory.

There have been several threads about the light blue airboxes in the past. Here are a couple I found after a quick search.

I believe the consensus is in the North American market they were replacements obtained from the dealer. I found one on a parts car that had been hit hard on the drivers side and repaired, so I agree with the dealer replacement part theory.

I think I searched for grey air cleaner & came up with nothing. Thanks for response
