I am setting up a FCR on a 05 and figured i would set up the intake as well. I am looking to buy a dasa filter adapter. Should i switch out the 05 boot for a 06 and up? Right now its a stock head with a pump gas venom piston in it with a rossier full pipe. I know the stock intakes make good power but which would be a better choice. The 06 looks like a smoother transition from the large filter than the 05. I cant tell but does the 06 have the resonator hole close to the carb end? If not that would be a plus as well?
