I'm pretty much done with my ITB set up. Its made up of an OBX manifold chopped up with honda 929 throttle bodies. I just wanted to know what would be more beneficial?

V-stacks alone?
or V-stacks with an airbox built around them with a tube that extends to where an intake filter would be?

i was thinking would the airbox restrict how much air the ITB's can take in..?

 

Air box for daily driving and no box for track or weekends
