Hey guys! I was just wonder what kind of modification can you do to the airbox??? I have an '84 4000 s, non turbo with no cat,and a K&N filter. I noticed the opening for the airbox comes from an apprx. 2 to 3" pipe from the side of the car to the bottom of the box. (Is that right?) Is there anything I can do to this airbox, is there any boxes one could buy? Raj AUDiocee (always experimenting with new ideas!)
