| The cast aluminum design is more durable than the factory composite. "Boost" or "spray," the 300-111 can handle the added stress of forced induction and nitrous injection. It contains extra material for flow modifications (hand, CNC, or Extrude Hone") to feed hungry modified LS1 engines. The aluminum manifold's thicker walls can also be machined for NOS fogger nozzles or other modifications.
