Been researching Cold Air Intakes for my V6 and there seems to be just as many cons as pros for having one. I'm seeing a lot of people say it actually could make your car perform worse under daily driving conditions, and is only an asset at high rpms. How do you know who's right or wrong? I also don't know if I would be better off spending the money on a CAI or a Tuner. I don't want to get any codes for any modifications I make, and I'm not in a big city where getting help would be easier. Any thoughts?
