Have you guys ever seen something like this before? It’s a first for me. I havnt looked inside the cross intake as of yet As to how much space there is for a conical filter , I’m not sure. Also not sure how it holds there , glue , just a tight fitment who knows. . Also I doubt it would give you an intake sound with the stock box. Would it increase airflow? I would think so but I’m not sure. But anyway a 3D printed adapter is an interesting idea at least.
