GMC Sierra 1500 Throttle Body Spacer - aFe - Silver Bullet - Silver - `07-`13. A precision-engineered throttle body spacer designed for 2007–2013 Sierra 1500 trucks to improve intake airflow characteristics and sharpen throttle response.

The aFe Silver Bullet spacer uses a patented serrated/helix entry design (US PAT 07055513) to create controlled air turbulence just before the intake manifold. That turbulence increases intake air speed and pressure at the point of entry, which can improve throttle response and overall engine efficiency without modifying the factory throttle body. CNC-machined from 6061-T6 billet aluminum and finished in durable silver, this spacer installs using all factory mounting locations and includes a supplied gasket for a proper seal and straightforward installation.
