After looking at Nosqueezes mods, I have actually been tempted and do want to mod my element a little bit. Im looking to drop no more than 400 bux on modding one aspect of the car itself, I was thinking about the cold air intakes, how much would one of those babies cost, and are they easy to install? Also are their noticeable performance enhancements after installed. What does the cold air intake actually do, from what I understand it filters out harmful debris to the engine and possibly effects gas mileage and speed? Thanks for any help,!!
