Description
The aFe Silver Bullet Throttle Body Spacer (afe46-38011) improves airflow efficiency and throttle response on Toyota 4Runner and FJ Cruiser models equipped with the 4.0L V6 engine. Its serrated/helix design creates controlled intake turbulence before the combustion chamber, promoting more complete combustion for increased horsepower and torque, while also reducing intake whistle.
