Mercruiser Short Runner Manifold Conversion

**Available on exchange basis**

Arizona Speed and Marine’s “Short Runner” Extrude Honed intake manifold is essential when extracting the most HP and Torque out of your MPI or Magnum EFI engine. First, the manifolds are precision CNC machined to unshroud the intake runners and shape the inlet. The manifolds are then Extrude Honed to further increase airflow. The reduction in overall runner length extends the RPM range of the engine, for increased HP and Torque. These manifolds are available on an exchange basis.
