Searched, but no luck...They have diff part #'s for each. On JWT website, the 350z part # is P3503-1XCN7...for the G35 it's PG353-1XCN8. I'm thinkin it may be due to the difference in hoods maybe....the heat shield seals up to the underside of the hood. Anyone know for sure what the difference is?? I want to get the Z tube also, so if the difference is tube-related, then I may need the Z part #....if it's the hood, well you know, I just need to figure this out....thanks..all input is greatly appreciated...

Well if you can take off the stock intake tube and connect the Z tube to the stock airbox, there shouldn't be an fitment issue. But get a Z tube first, the popcharger is practically useless without it.

The difference between the two is in the heat shield only. The "Z" heat shield is closed. The "G" has an opening pointing toward the center hood scoop in the "G". There is material to mate the shield and the scoop up. The filter itself is exactly the same.
