Hello i have been looking at cold air intakes and how they work. It seems no one can agree if they are a silly gimmick or a great way to add horsepower. Also if its worth it what design is the best for a VT regarding horsepower. I am also wondering about how they sound. i live right next to the police station, will they be hassling me because my car sounds like a jet engine? I am not looking to race or anything but i would love to see a stock VT vs one with a CAI, if anyone has seen anything like that. Some people have said it has more effect the more bolt ons you have, is that the case?
