Well to start off it's a very broad statement and i can't find it on here. I'm looking to buy a cold air intake and all i can find is short ram ones. I want a real cold air but the ones i found arn't street legal in which means i can't pass emissions without proper C.A.R.B. legal paperwork. If you guys some how found a real street legal cold air that can pass emissions and or own one help would be appreciated. It was hard enough with my new exhaust system to pass emissions. If you were wondering I have a 92 S13. Thanks. And if this is the wrong section I'm sorry.
