Silver Bullet Throttle Body Spacer

Serrated/Helix Design:
The serrated/helix design (US PAT 07055513) creates turbulence in the intake manifold and increases air pressure in the combustion chamber for better performance. This unique entry design also reduces intake whistle that commonly occurs with other helix-only styles.

Longer Intake Tract:
The addition of a Silver Bullet throttle body spacer lengthens the intake tract, which increases air intake speed, resulting in improved throttle response and overall performance.

6061-T6 Billet Aluminum Construction:
All Silver Bullet throttle body spacers are precision machined from 6061-T6 billet aluminum for lightweight, high strength, and a beautiful finish.

Simple Installation:
This Silver Bullet throttle body spacer's inset style makes for an easier fit into the E36's compact engine compartment. It includes all hardware necessary for installation.
