What is a throttle body spacer and how does it work?

A throttle body spacer fits between your throttle body and intake manifold. It creates a slight turbulence in the incoming air charge, which can help improve throttle response and fuel efficiency by ensuring a more complete burn.

Will this throttle body spacer make my truck whistle?

This aFe Silver Bullet throttle body spacer uses a unique serrated/helix entry design that creates the necessary air turbulence without the annoying whistle sometimes found in other helix-only throttle spacers.

What material is this throttle body spacer made from?

The aFe Silver Bullet throttle body spacer is constructed out of durable T-6061 billet aluminum, ensuring it holds up well under the hood.
