I drive a 2006 Saturn Ion 2.2L. I've been doing the many basic repairs that come. However, the question was posed if a cold air intake would be a good idea to get better mileage and power out of the car. I have heard the argument that the Saturn was not made to use a cold air so it would do more harm than good in the long run. What is the opinion of the community, i would like to understand the pros and cons and the whys and why nots. Any help is a appreciated.
