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.BladeRunner intake manifolds from aFe Power provide smooth and direct airflow for minimal pressure loss and maximum CFM gains. How do they do it? With innovative MDV technology that uses smooth bends and directional vanes to form multiple paths through the manifold. These paths are smoother and shorter, producing much smaller dead air zones, for increased overall airflow to the engine. You can also expect faster turbo spool-up, improved boost pressure, and an increase in horsepower and torque! BladeRunners are available in configurations for a wide range of vehicles from the 1990s and up. Additional features include: * Proprietary internal bolt design guaranteed not to deform or leak * Cast A356-T6 aluminum construction * Up to 5 port pads (depending on application) threaded for 1/8 in. NPT * Stainless steel hardware
