We have looked at dyno data, before and after on multiple cars run by independent and credible facilities, not the marketing stuff the purveyors of these systems post on the internet. The gains, if any, were in the range of reproducibility error, and then only at extreme RPM.... The factory intake system is pretty good, the aftermarket intakes added little if anything, other than making your wallet easier to sit on................
