How does the Serrated/Helix design improve performance?

The Serrated/Helix design creates turbulence in the intake air. This turbulence helps break up the fuel spray, leading to a more complete combustion cycle. This can result in increased horsepower, torque, and a more responsive throttle.

Is this throttle body spacer difficult to install?

No, this spacer is designed to use all factory mounting locations. This means it fits right and provides stability for a hassle-free installation without needing extra parts.

Can this part be shipped to California?

No, this throttle body spacer is not CARB approved and cannot be shipped to California due to emissions regulations.
