Larger Bore Throttle Body
This aFe POWER throttle body features a 70mm bore, allowing significantly more airflow than the factory 65mm unit. The increased airflow improves throttle response and supports additional power gains, especially when paired with intake and exhaust upgrades.
6061-T6 Billet Aluminum Adapter
The included adapter is precision CNC-machined from 6061-T6 billet aluminum for excellent strength, light weight, and a perfect fit. Its serrated/swirl design helps create intake turbulence, promoting better fuel atomization for more complete combustion, increased horsepower, torque, and improved throttle response.
Simple Installation
This throttle body kit installs using factory mounting locations and plug-and-play electronics, making installation quick and straightforward. All required hardware and gaskets are included for a clean, secure install.
Installation Note
For optimal performance gains, it is recommended to pair this throttle body with an aFe POWER cold air intake system.
