    Serrated/Helix Design:
    The serrated/helix design (US PAT 07055513) creates turbulence in the intake manifold and increases air pressure in the combustion chamber for better performance. This unique entry design also reduces intake whistle that commonly occurs with other helix-only styles.

    Longer Intake Tract:
    The addition of a Silver Bullet throttle body spacer lengthens the intake tract, which increases air intake speed, resulting in improved throttle response and overall performance.

    6061-T6 Billet Aluminum Construction:
    All Silver Bullet throttle body spacers are precision machined from 6061-T6 billet aluminum for lightweight, high strength, and a beautiful finish.

    Custom Hardware:
    This Silver Bullet throttle body spacer includes custom-made screws, designed specifically for your BMW. Created and machined in-house, our screws feature precisely positioned threads, allowing for a secure, factory-like, non-damaging connection to your plastic intake manifold.

    Silver Bullet throttle body spacers create turbulence in the air flow at the point just before entry to the engine – increasing performance, as well as improving throttle response and fuel efficiency.
