aFe Silver Bullet Throttle Body Spacer for 2001-2009 Ford Ranger, Explorer & Mazda B4000 (V6-4.0L)

Fits select 2001-2009 Ford Explorer, Explorer Sport Trac, Ranger, and Mazda B4000 (V6-4.0L).

The aFe Silver Bullet throttle body spacer is designed to optimize the air-fuel charge for improved engine performance. Precision-machined from durable T-6061 billet aluminum, this spacer features a unique serrated/helix entry design. This combination creates a turbulent vortex at the manifold entry, improving air volume and fuel atomization to increase horsepower, torque, and throttle response.

Unlike traditional helix-only spacers that often produce a distracting high-pitched whistle, the aFe Silver Bullet’s serrated design breaks up the airflow to eliminate noise while maintaining performance gains. This spacer is an easy-to-install upgrade that is compatible with both factory and aFe Power intake systems.
