AutoExe Carbon Fiber Ram Air Intake System
Application: Mazda RX-7
Part Number: MFD959

It is structured to take in more fresh air as the car runs more distance with the air intake directed forward the car.  Fresh air is not only efficiently taken in through the dedicated efficient filter, but also the insulation-efficiency and high-grade carbon is used in the main body.  Therefore, it produces the effect close to an incensement of engine displacement.  The sound of air taken in that you can hear even inside the car is comfortable, and your feelings of driving also run high.
