The two engineering studies above illustrate the importance of understanding how air moves within the entire intake system. And while the airbox is doing it's job of increasing performance, it's also cleaning up the engine bay and looking good.
It is fitting patchy. It is quiet for minutes to run normally. As you step on the accelerator, you will hear the sound of sucking air intensely.
The baked aerial crimp, the air box is also steady construction.
I felt it because I went out for a while. Intake sound comes from around 3000 turns. I feel that the boost is quick and sharp. With the feeling that the needle of the boost gauge also rises at a stretch. However, it seems that the torque in the low speed range, which is often said to have diminished. It is unknown whether it feels so with the force of inspiration sound. I wanted to try it in the high speed area quickly.
