As a heads up: after comparing the AAM intakes that I previously had to the inlets of the EPS TBs, one would assume that a larger diameter intake system would be benefical. The AAM intakes are 2.75" and the EPS inlets are appx. 3-3.25".

EDIT: I should also add that Admin Tuning advertises their 3" G37 intakes fit the 370z; I'm waiting on mine to arrive
