So after a few days of having my G35 I've been looking around and researching what to do.
Among many things I've read about the Plenum Spacer which enhances the engine sound somewhat and gives a little better performance (not expecting much).

So I have access to a CNC miller which could spit these out effortlessly if I had a CAD drawing with dimensions. Maybe even make some and sell them for a fraction of what I've been seeing on ebay etc?

Could this work.....

 

Don't be that guy. Not to mention infringement. Do what I do. Buy it, measure it, make it, sell the original.

 

Yeah, plus a lot of people here know/have been helped by/respect Tony (motordyne dude). I don't think anyone here is gonna condone that ripping his design.
