Roger on the V2... I've seen it. But the VRIS already "tunes" the intake manifold to 4 different RPM bands, kinda making the 2-tuned feature of the V2 redundant and maybe even detrimental. I'm curious to know if changing the air intake (to anything other than stock) will dork that VRIS "tuning" up and counteract any of the benefits of a CAI.

... and although I do appreciate your response, I already understand what a tuned intake is and (fundamentally) how it works. What I'm looking for are any principles and simple rules or equations that I could use in designing a tuned custom intake to make the most of my existing IM and VRIS. (Or, perhaps, to know with certainty that the V2 is tuned by design specifically for my engine.)

Thanks, again.
