The new Bladerunner manifold kit for the popular 7.3L Power Stroke is constructed of cast A356-T6 aluminum and features the patented MDV (Multiple Directional Vane) technology which helps increase intake velocity for increased flow, lower EGTs, improved MPG and faster turbo spool up times. This system contains one Bladerunner intake manifold which outflows the factory unit by 18% and one Bladerunner turbo outlet manifold that outflows the factory unit by 15%. This is a direct bolt-on system with all hardware and brackets requires for an easy installation. These manifolds also come with 1/8″ NPT ports for nitrous, gauges or testing probes.
