Intake Air Collector: Description and Operation

Intake Collector

The intake collector, located above the intake manifold is designed to increase horsepower over a broader rpm range. By having a larger space for
air to accumulate, the engine has better response when the throttle valve is opened abruptly. This also reduces the pulsed vacuum effect that is
more pronounced with a smaller manifold, allowing more precise control of the EGR valve.
