This Silver Bullet throttle body spacer produces 5hp and 7lbs. x ft. of torque.  The Silver Bullet throttle body spacer is constructed out of T-6061 billet aluminum and is designed using a serrated helix design which creates air turbulence which helps to improve volumetric efficiency.  The serrated helix design also helps to eliminate the annoying whistle found in standard helix designs.  This spacer kit includes the Silver Bullet throttle body spacer, gaskets, hardware and a torque tube for a clean installation.
