46-33010 | aFe Power Silver Bullet Throttle Body Spacer (2011-2020 F-150 V8-5.0L)

• Silver Bullet throttle body spacers create turbulence in the air flow at the point just prior to entry of the engine - increasing performance, as well as improving throttle response.
• Constructed from Durable 6061-T6 Billet Aluminum
• Unique Serrated/Helix Entry Design Creates Turbulence and Eliminates Whistle Sound
• Increases Air Intake Speed, Improving Performance & Throttle Response

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:
All Silver Bullet throttle body spacers are 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 gasket provides a perfect seal.
