The stock cast aluminum intake bridge manifold on the Ford 6.7L Power Stroke is a well-known performance bottleneck. Certain design characteristics of the stock manifold restrict fresh air intake, which is particularly unfavorable for engine performance. Some sections of the stock manifold's internal passage are even narrower than a 2.5-inch-diameter tube, severely limiting airflow. Additionally, the EGR inlet swirl is positioned directly in the center of the flow path, creating significant turb
