Then that must be the design for ALL subarus, because their airboxes are all interchangeable. It was also argued that the flex joint was part of a plan for velocity when that was grossly incorrect. Who would design an intake for engines with 1/3 more displacement to have equal designs to that of the lesser (the 2.2 I am referring to). From this I can only deduce that the airbox was used simply to keep it simple and not for performance. Why would you want a brick wall in the way of fast moving air??
