The aFe Silver Bullet throttle body spacer bolts between the throttle body and intake manifold on BMW V8 models, using a serrated/helix entry to create air turbulence that improves throttle response and low-end torque. It is CNC-machined from 6061-T6 billet aluminum with a black anodized finish, and the serrated design eliminates the whistle common to helix-only spacers. Uses the factory mounting locations for a bolt-on install.
