my f3 manual shows shorter ones on the outside... i dont think the shorter they are, the more air goes in. not trying to argue you wrong, because i really have no idea. but MY assumption would be that they are set up L:sm, lrg, lrg, sm:R to try regulating the flow of the air inside of the airbox, making kind of an aerodynamic to provide all cylinders with an even amount of air.....
