The BladeRunner 3.5 intake manifold represents the next generation in intake manifold design. The BladeRunner intake manifold uses the patented MDV (Multiple Directional Vane) technology to guide the air through the manifold maximizing air flow. Constructed out of cast A356 - T6 aluminum and using a proprietary internal bolt design helps increase air flow and provide a solid seal void of leaks or deformities. The 3.5 BladeRunner intake manifold comes with 5 ports (2 are tapped at 18 NPT) built - in for nitrous injection, gauges and other accessories used by hardcore enthusiasts. In recent testing the BladeRunner intake manifold outflowed the factory intake by 68. This intake is specifically designed to provide increased intake volume and air velocity for the hardcore diesel racer and enthusiast.
