Raw Brokerage Pro-Flow Intake Manifold - RB26DETT

To combat the flow restrictions and irregularities of the factory intake manifold; the Raw Brokerage Pro-Flow Intake Plenum promotes maximum airflow to all six cylinders of the powerful RB26 engine.  This plenum eliminates the factory individual throttle bodies, linkage system, and casted plenum.  Replacing these components is a plenum beautify TIG welded along every seam that have held up to 1500hp and 45+psi of turbo boosting abuse.  Mating it to the factory manifold is a precisely CNC machined flange with smooth intake runners to the tapered fabricated inlet plenum.  This runner design removes the from factory poorly matched 3-piece runner design that causes turbulence within the runners where casting lips may appear from misalignment.  To retain the factory injector angle, port size and shape; the factory portion of the manifold that bolts the cylinder head has be reused.  This is also beneficial to those who have ported their cylinder head to match the intake runners and intake gasket.  Included is a large 90mm single throttle body that is perfectly matched to the plenum allowing more air to rush into the intake manifold.
