Is the only difference the fact that the 05-06 now have built in velocity stacks? Do the 05-06 airducts (tube in between airbox and TB) still have the resonator in the middle?

I was going to upgrade to the 06 350Z airbox and air duct but i called Performance Nissan and they said that it probabley wont fit. So maybe ill just go with a 06 G35 airbox if there is no difference.

Anybody know the differences between the 03 g35 airbox and the 06 g35 airbox? Anybody know the differences between the 06 g35 airbox and the 06 350Z airbox?

i don't know year-to-year, but yea, 350z intake box doesn't overlap on the G
