AFE Throttle Body Spacer

00-09 Dodge Dakota / Durango (4.7L & 5.7L Hemi)

46-32003

Serrated/Helix Design – US PAT 07055513

Unlike basic spacers, the Silver Bullet features a patented serrated/helix internal design that creates controlled air turbulence as it enters the intake manifold. This effect helps:

Increase air pressure in the combustion chamber

Improve atomization of the air-fuel mixture

Enhance throttle response and combustion efficiency

Additionally, this design reduces annoying intake whistle, a common issue found in helix-only spacers.

Longer Intake Tract = Faster Air Speed

By lengthening the intake tract, the throttle body spacer naturally increases the velocity of incoming air. The result is a noticeable improvement in throttle response, low-end torque, and overall engine performance—especially during acceleration.

6061-T6 Billet Aluminum Construction

Crafted from premium 6061-T6 billet aluminum, this spacer is:

Lightweight for optimal power-to-weight balance

Durable and corrosion-resistant

CNC-machined for exact fitment and flawless finish

This ensures long-term performance under high-heat engine conditions.
