AIR CLEANER
The air inhaled in the throttle fully open is huge and super fast. On the other hand, inertia works during the throttle OFF, and the intake is compressed in front of the closed throttle. Next, when the accelerator is opened, the cleaner box sealed by the compressed recoil increases the negative pressure, which increases the filling efficiency. In this way, the intake system of Honda NA is very clever and important. The best air cleaner is a dust -proof effect that is effective for rainy dust while reducing the resistance of inhalation air.
