Overview

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.

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