aFe Silver Bullet Throttle Body Spacer (46-33009) is designed to enhance horsepower and torque for 2001–2009 Ford Ranger/Explorer SporTrac with the V6-4.0L engine. Constructed from durable T-6061 billet aluminum, this spacer features a unique serrated/helix design that creates turbulence in the air intake, improving throttle response and fuel efficiency. Unlike other throttle body spacers, the aFe Silver Bullet spacer eliminates the annoying whistle by incorporating the serrated edge. This spacer also increases volumetric efficiency by raising the air volume between the throttle body and the engine, allowing for a more complete burn and better overall engine performance.
