Sheet Metal Plenum Intake Manifold 70mm
Over the years we have tested these sheet metal intake manifolds on many differing combos with great success. This is a great next step from a port matched factory intake manifold.
By cutting the plenum off this enables us to fully port every runner all the way through to allow maximum possible airflow given the casting capabilities. On top of the runner cross sectional gains we fabricate a larger plenum to increase the volume and machine the throttle body opening to 70mm which is max given the stock perimeter bolt pattern.
This intake would be well suited for naturally aspirated builds seeking higher rpm potential with big power gains above 4,000 rpm's. Boosted applications benefit such as roots, centrifugal and turbo's actually spool faster.
