aFe Silver Bullet Throttle Body Spacer - BMW X5, 545i, 550i, 645Ci, 745i N62 V8 (1997-2009)

The aFe Silver Bullet throttle body spacer installs between the throttle body and intake manifold on N62 V8 BMWs, spanning the X5, 5 Series, 6 Series and 7 Series. Its serrated/helix entry creates turbulence at the manifold to improve throttle response and low-end torque, without the whistle produced by helix-only spacers. It is precision machined from durable T-6061 billet aluminum and works with aFe intakes.
