・Carbon air duct + dedicated air filter ・Maintenance kit included ---------------------------A high-end model that pursues efficiency and looks.The "Ram Air Intake System" was born from the idea of pushing in air with supercharging = ram pressure. Since it depends on the vehicle speed, positive pressure is rarely applied, but the effect of efficiently taking in air with high oxygen density that is not affected by the radiant heat of the engine is great. 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, promoting fuel injection. The basic configuration consists of an intake duct (excluding some models) that draws in fresh air from the front of the bumper, a large-capacity cleaner box specially designed for the intake path, and a low-resistance wet air filter that can be cleaned with the included maintenance kit. The length and inner diameter of the intake pipe are also optimized for each model and engine, providing powerful acceleration from the moment you step on the accelerator. The appearance made of real carbon also has a high-quality taste.
