I ripped out a couple of those brass rivlet's. So I got a used airbox off eBay and removed my airbox. I was wondering though if I remove the whole throttle body piece with the velocity stacks too and the injectors and just swap everything on to the new airbox, do i need to do anything else? Shouldn't these things be so close to identical there is nothing that the dealer needs to reset or tune? Any thoughts? Thanks.
