Heavy Duty Intake Manifold Actuator (2721402401RPRM) by URO Parts®. A common failure inherent to the intake manifold is for breakage of the actuating mechanisms on the intake swirl flap system. These flaps are designed to create intake flow turbulence improving low speed engine performance, enhancing fuel economy, and reducing emissions. A failure in this system will be detrimental to engine performance and will result in engine fault codes, CEL, and failed emissions testing. In addition, if not repaired quickly it could result in damage to other costly emission control system components.
