1999-2003 7.3L Ford Powerstroke
Intake Manifolds

The intake manifold on your 7.3L is the last line of defense for providing high velocity, smooth airflow into your engine.  Unfortunately, the stock manifold features hard bends and bottlenecks that inhibit overall airflow, thus causing a restriction and limiting the full potential of other airflow accessories, such as upgraded cold air intakes, intercoolers, and especially upgraded turbos.  Besides purely functional, an upgraded intake manifold also looks pretty impressive when you pop the hood!
