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.
