you could use a hks adapter and run a piece of pipe down thru the snorkel hole and mount the filter behind the bumper. they get quite dirty quick running there tho. but like was said all ive ever seen was the arc box and very rare.
Put the filter THROUGH the snorkel hole mounted onto the AFM. Then for even better cooling (This is like uber leet ultra cooling) wrap all the pipes (This wouldn't really work for rubber, it would be kinda awkward) with thermacore or some kind of heat resistant wrap, then put a sort of heat shield blocking as much heat from the engine to the pipe as possible. Using a dryer duct from the front/fog light delivering cold air works very well also, but as stated the filter will get dirty pretty quick.
