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.
