AFE Silver Bullet Throttle Body Spacer (06-11 Civic Si)Find parts that fit my vehicle

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). 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. Adding a Silver Bullet Throttle Body spacer lengthens the intake track which helps increase intake air speed, performance and improve throttle response. This Silver Bullet throttle body spacer uses all factory mounting locations, making for a hassle-free installation. A supplied gasket provides a perfect seal. This item will only fit models equipped with the factory intake system.

Whether its for a full rebuild or some standard maintenance, the proper engine components are needed to make sure your vehicle is running smooth.

Throttle bodies are the main component of your vehicle that regulates the amount of air entering the engine. Since throttle bodies have a butterfly valve, they control the amount of air that enters the intake manifold. If you are looking for more power in your vehicle, consider upgrading to a larger throttle body that allows for more air flow.
