It is an impression with the above three types of intake system attached.
So far, I have tried the effects of each by wearing them individually.
With the combination of the air filter and the intake pipe, the response at low rpm became poor and I removed it once, but I felt the torque increase in the middle and high rpm range.

With the combination of the air filter and the air guide, I felt the response improved and the rotation increased.
After installing the fresh air guide, the hole in the cut part at the top of the bumper was enlarged, and the rotation increased faster from low rotation to high rotation, but I did not feel the power feeling so much.

After that, when I tried to see what would happen if I attached the intake pipe again, the response became slightly rounded and the corners were removed, making it easier to handle, and is it a synergistic effect?It has grown considerably even at high speeds.
Since it is a non-turbo car, torque does not come out when you step on the accelerator, but the rotation smoothly rises like a naturally aspirated engine and a pleasant rise continues until high rotation, and the rotation does not slow down to the front of the red zone. I came to go.
