Caravan AWD V6-201 3.3L (1991)
Intake Manifold: Description and Operation
The intake manifold is a tuned two-piece semi-permanent mold aluminum casting with individual primary runners leading from a plenum to the
cylinders. The manifold is designed to boost torque in the 3600 rpm range and contributes to the engine's broad, flat torque curve, which was desired for
excellent engine tractability, response and usable power output. The intake manifold is also cored with upper level EGR passages for balanced cylinder
to cylinder EGR distribution.
