Power Plus 52031 High Performance Intake Manifold

No other performance intake manifold on the market is available with all the features and benefits found in the Power+Plus High Performance Racing Manifold.  These 360° manifolds feature dual distributor hold downs for Chevy, four corner water outlets, and line of sight port configuration.  They also have extended port dividers, thermostat recess, and an accessory bracket boss and tapped hole.  There is an air gap under the front water crossover for extra cooling and an extra tapped water port. 

These manifolds have permanent mold castings for accurate port placement, tighter grain castings, and less porosity.  They have nitrous bosses, measure 5.12" from carb base to bottom of manifold, and are available in satin finish or polished (the area under the intake runners is not polished).  Available plain or polished. 

RPM range: 3000-7500
