Description
The aFe Silver Bullet Throttle Body Spacer (afe46-38009) enhances airflow and throttle response for Scion FR-S, Toyota 86, Subaru BRZ, and international FT86/GT86 models. Its serrated/helix design creates turbulence in the combustion chamber for more complete combustion, resulting in increased horsepower and torque while reducing intake whistle.
Key Features
- CNC-Machined 6061-T6 Billet Aluminum Construction – Lightweight, high-strength, precision machined for perfect fit and finish
- Serrated/Helix TBS Design – Optimizes airflow for maximum combustion efficiency and reduces intake whistle
- Dyno-Tested Performance Gains – Up to +5 HP and +4 lbs. x ft. torque
- Longer Intake Tract – Increases intake air speed for improved throttle response
- 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 aftermarket intake systems
