Removed the air flow meter, which is a major factor in suction resistance, and converted it to D JETRO. And the new intake tune from now on will be controlled by "F-CON V Pro". Especially when combined with HKS Racing Suction, the effect is enormous. It is this "air flowless adapter" that makes it even easier to convert to D JETRO. By replacing the buffed aluminum casting pipe with airflow, the suction system is easily completed. In addition, a boss (processing required) for attaching an intake air temperature sensor etc. is provided on the pipe.
