Engine Intake Manifold - 1-147-032

The Speedmasterª MidRise manifolds, along with the similar MidRise Air, are the most powerful dual plane manifolds available. For non-pollution controlled street machines, these are among the very best manifolds you can use. They feature a square bore carburetor flange, nitrous bosses, four corner water ports, and dual distributor hold downs. These manifolds are approximately 5/8"“ taller than the LowRise series. On medium horsepower engines, dyno tests have shown that this manifold comes very close to producing similar power and torque numbers as our shootout racing intake manifold.
