How does the Serrated/Helix design improve performance?

The Serrated/Helix design creates turbulence in the air entering the combustion chamber. This turbulence helps break up fuel droplets, leading to a more complete burn and potentially increasing horsepower and torque.

Is this throttle body spacer difficult to install?

No, this spacer uses all factory mounting locations. This means it should install directly without needing any modifications, making it a straightforward process.

Can this be shipped to California?

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