aFe Silver Bullet Throttle Body Spacer - BMW 545i, 550i, 650i, 750i, X5 4.4L / 4.8L V8 (2000-2010) - Black

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.
