Auto Exe Ram Air Intake System Mazda RX-7 1991-2003

The "Ram Air Intake System" was created based on the idea of supercharging from the running wind, which means pushing in air using ram pressure. In reality, positive pressure is rarely applied, but as the vehicle speed increases, the effect of efficiently taking in air with high oxygen density is significant. Our system aims to improve power and torque by increasing the amount of intake air within the mass-produced ECU's A/F (Air/Fuel air/fuel ratio) correction margin to encourage fuel injection. The basic structure consists of an intake duct that takes in fresh air from the front of the bumper (excluding some models), a large-capacity cleaner box with a specially designed intake path, and a low-resistance wet air filter. The length and inner diameter of the intake pipe are also optimized for each vehicle model and engine, providing powerful acceleration from the moment you start stepping on the accelerator. The exterior made of real carbon also has a high-quality feel.
