Immediately after mounting, I was able to experience the power-up in the entire area.
In particular, the feeling of comfort in the high rpm range has increased, making driving more enjoyable.
After a while, I returned it to the genuine product, but the car felt heavy.

If you install it according to the instruction manual, the lower part of the suction kit and the hose band will interfere, and in the worst case, a hole may be opened, so please correct the instruction manual.
