The aFe Silver Bullet throttle body spacer installs between the throttle body and intake manifold, using a serrated helix entry to create turbulence in the incoming charge for sharper throttle response, added low-end torque and better fuel economy. It is precision-machined from T-6061 billet aluminum, and the serrated design eliminates the whistle common to helix-only spacers. Fits the N55 3.0L across the BMW 135i, 335i and 435i (F30/F32), plus the M235i and X1 xDrive35i, and is compatible with aFe intake systems.
