      Description

      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.

      • CNC-Machined from Durable 6061-T6 Billet Aluminum
      • Unique Serrated/Helix Entry Design Creates Turbulence and Reduces Whistle Sound
      • Increases Air Speed, Improving Performance and Throttle Response

      Serrated/Helix Design

      The serrated/helix design creates air turbulence in the intake manifold. This turbulence increases the air pressure in the combustion chamber, resulting in increased performance and improved throttle response. The serrated/helix combination design also reduces intake whistle that occurs with helix-only designs (US PAT 07055513).

      6061-T6 Billet Aluminum Construction

      This Silver Bullet throttle body spacer is precision machined from 6061-T6 billet aluminum for lightweight, high strength, and perfect fit and finish. Its black anodized finish gives a stealthy look.

      Longer Intake Track

      Adding a Silver Bullet Throttle Body spacer lengthens the intake track which helps increase intake air speed, performance and improve throttle response.

      Installation Is A Snap

      This Silver Bullet throttle body spacer uses all factory mounting locations, making for a hassle-free installation. A supplied gasket provides a perfect seal.
