On the GruppeM intake for the Porsche 964 3.6L 1989-94 , the factory ductwork is replaced with heat-shielding carbon fiber with enhanced inlets to capture the maximum amount of air. Lower intake air temperatures carry higher concentrations of oxygen, allowing for more energetic explosions and producing more horsepower and torque. Of course, reliability is never sacrificed -- high-efficiency, high-flow K&N air filter materials prevent contaminants from interfering with proper engine function.
