Does anyone have any experience with how this CAI performs on a 2007 5.3L yukon? Does it improve fuel economy? Will I see a HP gain? My goal is to improve fuel economy.
GM seems very tight lipped on the performance specs for this accessory. Is that because it just looks pretty and doesn't do anything or maybe because they haven'ty documented it?
If I install an after market model, will that void the warranty on my 07 yukon?
