Cold Air Intake HP Debate - Is it worth it ?

My guess is that the small difference is due in part to the marginally better flow dynamics of cone filters; the rest may simply be due to leaning out the mixture via a small, but stable, misread on the MAF sensors, for example due to a variation in the diameter or orientation of the piping.

With tuning, the difference between them should be even less if that's the case, as you would simply set the mixture where you want it on both types of set-ups, rather than relying on mechancially induced effects.

Explain to me your theory of why the G3 should be vastly superior.

A: name a Honda motor that is superior to any other motor for making power, hondas rely on weight and high revving motors but in reality compared to any other choice are a horrible option for power.
B: point me at a rotary NA build that makes power... The wankel was and is a failure. Don't mistake the brilliance of the handling of rx7s and rx8s and their power potential.
C: you don't mean American, you mean displacement (which is the typical route for American muscle cars) which will always make more power on an NA build

So, since you have the Stillen CBE (which is a very nice sounding exhaust, BTW, with proven gains), you won't as much in the way of gains from intake (unless you get a tune).

I agree with other comments that the OEM intake is well designed. I went with K&N drop-ins, and like the combo with my aftermarket exhaust.
