What is the benefit of the Serrated/Swirl blade design?

The Serrated/Swirl combination design creates intake turbulence. This turbulence helps break up fuel particles, leading to a more complete combustion cycle. This can result in increased horsepower, torque, and improved throttle response.

What other parts does aFe recommend installing with this throttle body?

aFe recommends installing this throttle body kit with an aFe cold air intake. They also suggest using a new, larger coupler at the throttle body with an inner diameter of 3.75 inches (95mm) for easier installation.

Is this throttle body legal for sale in California?

No, this throttle body is not CARB approved and cannot be shipped to California due to emissions regulations. It is also subject to California Proposition 65.

About this part

Product Details

This aFe POWER 90mm Throttle Body and adapter kit improves engine air flow over the stock 80mm throttle body. The extra air flow will increase horsepower and throttle response. Performance gains will be more noticeable as more upgrades are added to the vehicle. All adapters are constructed from 6061-T6 billet aluminum and are precision machined for light weight, high strength, and perfect fit and finish. The Serrated/Swirl combination design creates intake turbulence in the combustion chamber which breaks up the fuel creating a more complete combustion cycle increasing horsepower, torque and improving throttle response. This aFe POWER 90mm throttle body kit uses all factory mounting locations providing stability and a hassle-free installation. All needed hardware is included with the kit. It is recommended to install this throttle body kit with an aFe cold air intake. A new larger coupler at the throttle body is recommended for easier installation (coupler I.D. of 3.75” or 95mm at the throttle body).
