I will try and address the questions thus far. You definitely need the recirc kit and they played with it a bit at the tuners I think and it is also adjustable, you can get different springs and outlet adaptors for it to make different sounds. I am too old for silly sound effects and wanted no lag. Before the recirc kit and tune it stuttered a little with balls to the wall driving. Keep the ECU happy by returning the air back to the stock air intake.
