Construction & Design

The aFe Silver Bullet Throttle Body Spacer is crafted from high-grade 6061-T6 billet aluminum, a material known for its excellent strength-to-weight ratio and corrosion resistance. CNC machining ensures tight tolerances and a perfect fit, maintaining the integrity of your intake system. The spacer’s distinctive serrated and helix pattern is engineered to induce controlled turbulence, which promotes better air-fuel mixture and combustion efficiency.

This design not only improves airflow dynamics but also minimizes the intake whistle noise that can detract from the driving experience. The spacer’s robust construction guarantees long-lasting performance under the demanding conditions of daily driving and spirited use.

Performance & Sound

By increasing air velocity and creating turbulence within the intake manifold, the Silver Bullet throttle body spacer enhances throttle response and overall engine performance. Drivers will notice a more immediate and crisp throttle feel, contributing to a more engaging driving experience. Additionally, the unique serrated/helix design reduces the typical intake whistle sound, resulting in a quieter and more refined engine note.
