What is the main benefit of installing a throttle body spacer?

A throttle body spacer creates turbulence in the air entering your engine. This can result in increased horsepower, torque, improved throttle response, and better fuel efficiency.

Does this throttle body spacer make noise?

No, this aFe Silver Bullet throttle body spacer uses a unique serrated and helix entry design that creates turbulence without the annoying whistle often found in other helix-only spacers.

What material is this throttle body spacer made from?

The spacer is constructed from durable T-6061 billet aluminum, which is both strong and lightweight.
