In the long run, it will definitely be worth the investment. Research shows that a car with 30MPG saves the driver 600+ dollars in a year when compared to a 20MPG car. So, 2-3MPG equals $60-100. And while that might not sound like a lot, in five years, you’ll get to save up to 500 bucks, and that’s decent money. You’ll be able to buy a new, top-of-the-line cold air intake and still save some for the rainy day.
