Throttle body spacers are designed to increase the distance between the throttle body and the intake manifold. This can help to increase the volume of air entering the engine and improve horsepower and torque.
Electronic throttle controllers, or throttle boosters, are devices that modify the signal sent from the accelerator pedal to the engine control unit (ECU). This can improve throttle response and acceleration which adds more power and makes the car more eager to accelerate.
High-flow throttle bodies are designed to allow more air into the engine by increasing the size of the throttle body. This can help to improve horsepower and throttle response.
Besides all of the components mentioned above, other mods that can improve your Bronco’s throttle response are:
Performance Air Intake Systems
Throttle modifications can be worth it if you are looking to improve your vehicle's acceleration and throttle response. Some throttle modifications can increase the amount of air flowing into the engine, which can result in improved performance and better throttle response.
However, you do need to keep in mind that some of these could void your warranty, so be sure to check that out in advance.
