How does this throttle body spacer improve fuel efficiency?

By creating turbulence in the air entering the engine, the spacer helps optimize the air-fuel mixture. This more efficient combustion can lead to improved fuel economy.

What is the benefit of the serrated/helix entry design?

The unique serrated/helix entry creates the necessary air turbulence for performance gains. It also specifically eliminates the whistling noise that some other helix-only throttle spacers produce.
