aFe Silver Bullet Throttle Body Spacer for 2004-2012 Chevrolet/GMC/Hummer (L5-3.5L / 3.7L) 46-34018

Fits select 2004-2012 Chevrolet Colorado, GMC Canyon, Hummer H3, and Isuzu i-350/i-370 (L5-3.5L / 3.7L).

The aFe Silver Bullet throttle body spacer is designed to optimize intake airflow by creating turbulence at the point of entry into the manifold. Utilizing a patented serrated/helix design (US PAT 07055513), this spacer increases air velocity and pressure within the combustion chamber for improved throttle response and low-end torque. This unique serrated/helix combination also eliminates the high-pitched whistle common in helix-only spacer designs.

Every Silver Bullet is precision CNC-machined from 6061-T6 billet aluminum for exceptional strength and weight savings. The spacer features a black anodized finish for long-term corrosion resistance and a stealthy look under the hood. Installation is simple, as the unit bolts directly to factory mounting locations and includes a high-quality gasket to ensure a leak-free seal.
