Function and Benefits

The intake manifold channels air from the throttle body to each engine cylinder, while the throttle body regulates airflow based on driver input. Together, they form the backbone of the air induction system, ensuring the right mixture for efficient combustion. A faulty manifold or throttle body can cause rough idle, reduced performance, or poor fuel economy. Replacing this assembly restores factory performance.
