Has anyone given any thought to the new rule regarding the air intake and how you may address this on an IT 240sx? We built a custom air box to insulate the filter from the hot air of the engine compartment and would like to continue using it. From just the looks of some of the "cold air" systems out there one would think that there would be some benefit from the smooth flow of those intakes as opposed to the "boxy" stock unit. Weapon R has a neat "looking" system but I really wonder how these units perform. Any ideas, suggestions, experiences, etc...???
