The factory intake design has the foundation for excellent performance, but much of this is sacrificed in an effort to meet other design requirements. With requirements set forth for only supporting factory power output levels, low engine sound levels and long service intervals, there is plenty of room for improvement. Performance intake systems increase performance primarily by improving mass airflow through the system while still proving adequate filtration. Expect greater horsepower and torque through the power band with a more direct and responsive feel upon pressing the throttle. Sounds from the engine and supercharger/turbocharger are enhanced and some may even experience better fuel economy depending on driving style.
