GMC Sierra 3500 Throttle Body Spacer - aFe - Silver Bullet - Black - `96-`00. This Silver Bullet throttle body spacer is a direct-fit upgrade for 1996–2000 GMC Sierra 3500 trucks designed to increase intake air speed and improve throttle response.

The spacer uses a patented serrated/helix entry design to create controlled turbulence just ahead of the combustion chamber, which raises air pressure and reduces the intake whistle found with helix-only designs (US PAT 07055513). CNC-machined from 6061-T6 billet aluminum and finished in black anodize, the spacer adds length to the intake track while maintaining factory mounting points for straightforward installation. A gasket is included for a proper seal, and the spacer is compatible with Magnum FORCE intake systems 54-10301 and 51-10301 where noted.
