ENVY™ intake system is a direct drop-in replacement of the plastic transition pipe on E9X ///M3s. The main advantage of the ENVY™ Transition Chamber is the smooth delivery of intake charge from the RAM Air Scoop by its elimination of unnecessary notches and choked design points leading into the factory ///M3 airbox. Forced air makes its first contact with an organically designed transition chamber, which allows airflow from the ENVY™ Ram Air scoops to be naturally reserved and transitioned smoothly from left to right. All unnecessary turbulence was eliminated in the ENVY™ Transition Chamber’s design and conforms to extremely tight tolerances to provide a dramatic volume increase to charged air.
