The air filter replacement and air intake suction kit were replaced from the original parts in order.
By installing both, the engine speed increased quickly and I felt that starting was easier.
Also, the cruising distance after the accelerator was turned off was noticeably longer.
I was able to feel a big effect just by replacing the air filter first.
It is recommended because it is easy to work with.
