aFe Silver Bullet Throttle Body Spacer

aFe Silver Bullet Throttle Body Spacer - Toyota GR86 / Subaru BRZ (2022+)

Increased Intake Volume & Enhanced Throttle Response

Maximize the efficiency of your FA24 engine with the aFe Silver Bullet Throttle Body Spacer. This precision-engineered spacer is designed to improve the airflow characteristics of your intake system by creating a high-velocity air turbulence. By increasing the plenum volume between the throttle body and the intake manifold, the Silver Bullet helps your engine draw in air more effectively, resulting in improved mid-range torque and a sharper, more immediate throttle transition.

What’s Included in the Box:

- Silver Bullet Throttle Body Spacer: CNC-machined from high-grade T6-6061 billet aluminum.

- Extended Installation Hardware: Includes all necessary longer bolts for a secure fit.

- Internal Gasket/Seal: High-quality sealing surface to ensure a leak-free installation.

The aFe Advantage

- Serrated/Helix Design: The unique internal "Serrated Combination" design creates a vortex of air that breaks up the surface tension, allowing for better air/fuel atomization and a more complete combustion cycle.

- Billet Aluminum Construction: Precision-machined from a solid block of 6061-T6 aluminum for maximum durability and heat resistance.

- Increased Plenum Volume: By spacing the throttle body further from the manifold, it creates a larger "reserve" of air, which helps smooth out the air delivery during sudden throttle inputs.

- Direct Bolt-On Fit: Designed to fit perfectly between the factory throttle body and the intake manifold with zero modifications or drilling required.

- Lightweight Performance: Adds negligible weight while providing a functional gain in engine efficiency and a subtle induction whistle.

Precision Tip: This spacer is most effective when paired with a high-flow air filter or a cold air intake system. You may notice a slight "whistling" sound during part-throttle acceleration; this is a normal characteristic of the helix design as it pulls air through the serrated edges to create the beneficial turbulence.
