it might just. the stock air box pulls its air from behind the headlight right? well you dont get to much air from there, pull the head light out and you might get some decent airflow. the wizair is open there, and the hole in the fenderwall which problew flows more air in.
not saying you dont have a good setup but im sure the wizair out flows and keeps cooler temps. but i dont have numbers myself i cant really say anything. just mediforicaly. but im sure someone will chime in with some numbers
