So I've been sitting here building my dream list of things I'd like to do to my truck within the next year. One thing I came across was the Cervinis 07-12 Silverado Ram Air Hood(http://www.cervinis.com/07-12silverado-ram-air-hood.html). I know APM makes a Ram Air hood as well, but I like the look of the Cervinis a lot better personally. My question is, would this require an additional Ram Air intake as well? If so, does anyone have any knowledge or experience with the Banks system (http://www.autoaccessoriesgarage.com/Air-Intake-Systems/Banks-Ram-Air-Intake)? Lastly, would I realistically expect to actually notice much difference in performance? By the way, my truck is the 09 5.3L Crew Cab Silverado.
