What is an intake manifold runner control replacement?

An intake manifold control replacement occurs if the “butterfly,” a crucial valve in the air intake process, fails to open or close. This can cause significant damage to the engine.
An intake manifold control replacement requires a mechanic to perform a sophisticated diagnostic test to investigate your car’s overall airflow. In the event your mechanic discovers concerning data, it’s crucial to initiate replacement immediately.
Though it may not be something even your biggest gearhead friends are familiar with, the well-being of your intake manifold runner control could have serious implications for the overall performance of your car and the safety of you and your passengers.
