The aFe Silver Bullet throttle body spacer bolts between the throttle body and intake manifold on the 6.8L V10 Ford F-250, F-350 Super Duty and Excursion, using a serrated/helix entry to create turbulence that improves throttle response, torque and fuel efficiency. It is machined from 6061-T6 billet aluminum with a black anodized finish, and the serrated design eliminates the whistle common to helix-only spacers. Installs using the factory mounting locations.
