the only thing that will affect performance is hot air. More air/cooler air/ram air is always the goal of any intake. An open hole on the bottle of an airbox given that it is away from the engine is actually better for performance. The only draw back for something like that might be heavy rain or whistling but you guys are debating over something not very important..
