So I got a hold of a ‘19 GT air filter box and tube that my buddy had sitting around. I’ve been curious about the inner diameter tube size since the ‘19 doesn’t have the carbon trap/bracket/housing and honeycomb insert and the ‘22 does. Well I measured the inside diameter of the insert on my ‘22 and it measured 96.6mm and the ‘19 without it measured 98-99mm. Just like I suspected. The ‘22 definitely has some airflow restrictions in the form of carbon trap and its housing and the honeycomb insert. The honeycomb alone with the “thick” squares and smaller diameter should reduce the airflow. It may not be something gigantic but I bet is measurable on a cfm machine.
