Would it be ok to run an apex without the air box? Taped the foam over the inlets. Guy crashed in the back of another sled. What to finish the trip. What do you think.
 

It will run like that. Many on here run airbox mods and ram air top that open up the airbox.
These 4strokes are not as fussy as the 2smokes are. You won't burn down but may lack some performance as the incoming airflow will not be balanced and it will be loud.
