Description
The aFe Silver Bullet Throttle Body Spacer (afe46-38008) improves performance and throttle response for Toyota FJ Cruiser, 4Runner, and select Land Cruiser models by creating turbulence in the air flow just before entering the engine. This turbulence promotes more complete combustion, increasing horsepower, torque, and throttle responsiveness while reducing intake whistle.
Key Features
- CNC-Machined 6061-T6 Billet Aluminum Construction – Lightweight, high-strength, precision machined for perfect fit and finish
- Unique Serrated/Helix Entry Design – Increases air velocity and combustion efficiency while eliminating whistle sound
- Improves Air Intake Speed – Boosts performance and throttle response
- Longer Intake Tract – Enhances airflow for better engine efficiency
- Hassle-Free Installation – Uses all factory mounting locations; no modifications required
Serrated/Helix Design
- Combines serrations and helix to create turbulence in the combustion chamber
- Breaks up fuel for more complete combustion
- Reduces intake whistle common with helix-only designs
Fitment Note
-
Will not work with aFe POWER intake systems P/N: 51/54/75-76009 or 51/54/75-76010
