How does a throttle body spacer improve fuel efficiency?

By creating turbulence in the air entering the engine, the spacer helps ensure a more complete burn of fuel. This optimized airflow can lead to better gas mileage.

What is the difference between this spacer and others that whistle?

This aFe Silver Bullet spacer uses a unique serrated and helix entry design. This creates the necessary air turbulence without the annoying whistling sound often found in spacers with only a helix design.

What material is the aFe Silver Bullet Throttle Body Spacer made from?

The spacer is constructed from durable T-6061 billet aluminum, known for its strength and light weight.
