46-32004 | aFe Power Silver Bullet Throttle Body Spacer (2002-2007 Trucks V8-4.7L)

• 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 (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 includes all hardware necessary for installation.
