I've done back to back testing with them out of the box on a high 12 second car and it was identical in et and mph to the factory 70 RAIII iron intake.

Besides the aluminum version of the RAIV manifold that has numerous complaints on poor quality and not lining up with the ports on the heads what other aluminum factory intakes are being reproduced? I’m unaware of anything else, the OP stated that he doesn’t want one of those due to the numerous issues/complaints.
