How does this throttle body spacer improve performance?

The spacer creates turbulence in the air entering your engine. This turbulence helps the engine mix air and fuel more effectively, which can lead to increased horsepower, torque, and better throttle response.

What is the turbulence design on this spacer?

It uses a unique serrated and helix entry design. This creates a swirling effect in the incoming air charge at the manifold, helping to improve combustion.

Does this throttle body spacer make noise?

Unlike some other helix-only throttle spacers, this aFe Silver Bullet design is made to eliminate the annoying whistling noise, providing quieter operation.
