aFe Silver Bullet Throttle Body Spacer for 2011–2014 Ford Mustang, F-150 V6 3.7L

This precision-machined throttle body spacer improves intake airflow and throttle response by lengthening the intake tract and inducing controlled air turbulence. The serrated/helix geometry raises manifold air pressure for stronger combustion while reducing the intake whistle common to helix-only designs (US PAT 07055513). Machined from 6061-T6 billet aluminum with a black anodized finish, the spacer offers lightweight strength, a stealth appearance, and a direct-fit bolt-on installation using all factory mounting locations; a supplied gasket ensures a proper seal for an easy upgrade on 3.7L V6-equipped Ford Mustang and F-150 models.
