I previously have had a 2009 Mustang Gt500 and did a intake tune pulley to it for mods. I currently just purchased a white with grabber blue stripes 2011 GT500 with 1000 miles on it. My question is, its got the factory cold air intake, would there be any difference with the JLT Intake? Are the same mods for the 2011 the best mod for the money?
