Phoenix Extractor Manifolds - Spitfire & GT6

These manifolds from Phoenix, are designed with large diameter pipes and a 6-3-1 configuration for the six cylinder manifold and a 4-2 configuration for the four cylinder manifold. These configurations give maximum gas flow across a wide power band. The flanges ensure the manifold accurately aligns to the cylinder head. Both manifolds are designed to be compatible with either the Phoenix Big Bore Single Box System or Twin Box System.
