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.
