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 all factory mounting locations, making for a hassle-free installation. A supplied O-ring provides a perfect seal. This kit also includes a silicone coupling to guarantee perfect fitment and air flow with the factory air intake system. As the engine is only accessible from the trunk of the vehicle, this installation requires removing the engine cover between the trunk and the engine to access the air intake and will take around 1 hour.
This item will only work with factory air intake system
