aFe Silver Bullet Throttle Body Spacer (46-34018) improves airflow and throttle response for 2004–2012 GM Colorado/Canyon 3.5L/3.7L engines. This spacer features a serrated/helix design that creates intake turbulence, enhancing air pressure in the combustion chamber for better performance. The design also reduces the whistle common with helix-only spacers. Constructed from 6061-T6 billet aluminum, it delivers strength and precision while remaining lightweight. The black anodized finish offers a clean, stealthy appearance. By lengthening the intake tract, the Silver Bullet spacer increases intake air velocity, contributing to more efficient combustion. It installs using all factory mounting points and includes a gasket for a secure, leak-free seal.
