one of my buddies told me that it would be a good idea to add a velocity stack to my cold air intake. do any of you know if it works, or what it actually does? and is it really a good idea for me to get?
I have seen dyno results of them working. It allows for a larger opening air filter and a smoother flow of air. This was on SR20 powered cars using JWT velocity stacks but I don't see why the results would be any different. Don't expect a huge or even noticeable difference if you already have a regular CAI on the car. But every little bit counts.
