..umm to answer your first question I would have to say that the JDM is moderately larger. it effectively fills in most of the space left unused by the stock USDM one.
your second question I can't answer because I don't have an AEM CAI to compare it to.
I'd like to add, however, that the materials used to fabricate the USDM and the JDM are somewhat different. the USDM air intake box is made from a hard ABS plastic while its pipe/tubing is some sort of soft, rubbery compound. whereas the JDM TypeS uses the hard ABS plastic almost completely throughout. I have always thought that the USDM piping
might actually be soft enough to decrease in diameter under the slight vacuum conditions at high-throttle. since the JDM intake is hard plastic at this point, it
may actually hold the advantage (over the USDM) here because I doubt its diameter would change even under WOT

- Also you know that part that bulges out after the intake box?....would you say that has a larger overall diameter than an AEM CAI tube?
