aFe Silver Bullet Throttle Body Spacer - BMW 325i, 325Ci, 325xi E46 L6-2.5L (2001-2006)

The aFe Silver Bullet throttle body spacer installs between the throttle body and intake manifold on the E46 BMW 325i, 325Ci and 325xi with the 2.5L inline-six. 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.
