Cold Air Intake

Tim, Yes it should help with the gas milage. There are a few diffrent intake available for the H3 and it's a easy install. GM makes one that well be covered under factroy warranty. That the only thing I woould be carefull of. Not all of the after market intakes are going to be covered under warranty. GM all so makes exhaust system that is covered under the warranty. I don't know how fare you want to go with it. Here is a link to wants available from GM. http://www.gmaccessories.net/hendrickcadillachummer/ Jonathan
