We had this debate years ago, and Bob Larson (Flash) showed how the ports were necessary to smooth the airflow. Without them, or something like them, the airflow was worse and all of the benefits were not realized.
I cut the front out of the box and made a smooth surface for velocity stacks. I don't know if they help, but I do like how they look. Not that you can see them under the front cover.

I still think this is a waste of time and an air box for the meagre power gains, and thats only in the cold air days, when its hot and your drawing hot air you will possibly be down on power
For this to be of any real benefit you need to ensure the engine gets the coldest dense air possible, not hot engine bay air
Ask RS Barn
Each 10 degrees in raised air temp will cost you about 10BHP
