How does the Serrated/Helix design improve performance?

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

What material is the throttle body spacer made from?

The spacer is constructed from 6061-T6 billet aluminum. This material is chosen for its light weight and high strength, ensuring a durable and well-fitting part.

Can this throttle body spacer be shipped to California?

No, this aFe Silver Bullet Throttle Body Spacer is not CARB approved and cannot be shipped to California due to emissions regulations.
