aFe Silver Bullet Throttle Body Spacer (46-33002) enhances airflow for 2004–2010 Ford F-150 5.4L V8, boosting power, torque, and throttle response. Crafted from durable T-6061 billet aluminum, this spacer uses a unique serrated/helix entry design to generate turbulence at the intake manifold, improving air/fuel mixing without the annoying whistle found in helix-only designs. The increased plenum volume between the throttle body and intake manifold supports greater volumetric efficiency, resulting in improved combustion and fuel efficiency.
