The aFe Silver Bullet throttle body spacer bolts between the throttle body and intake manifold, where its serrated helix entry creates turbulence in the incoming charge for improved throttle response, added low-end torque and better fuel economy. It is precision-machined from T-6061 billet aluminum and its serrated design eliminates the whistle common to helix-only spacers. Fits the N20 and N26 2.0L four-cylinder across the BMW 228i, 320i, 328i and 428i (F30/F32), and is compatible with aFe intake systems.
