The “BOSS 3” is a complete system upgrade. By relocating the throttle body, replacing the Air Intake piping, providing a Cold Air Intake, and matching it to the “BOSS 2” system, the “BOSS 3” provides the ultimate in Performance. Relatively cost effective, a real “works” finish, easy to fit and minor (reversible) mods, the “BOSS 3” is a serious upgrade that will provide extreme performance levels for the XR6T.
