In order for the engine to function properly, a large amount of pure air must be sucked in. If harmful substances (such as dust, gum, aluminum oxide, acidified iron, etc.) in the air are inhaled, the cylinder barrel and piston components will increase the burden, causing abnormal wear of the cylinder barrel and piston components, and even mixing with engine oil, resulting in greater wear and tear, leading to engine performance degradation, shortening engine life, and preventing engine wear and tear. At the same time, the air filter also has a sound reduction function.

Air filters generally require replacement every 10000 kilometers to achieve optimal results
The performance that air filters should have
(1) Quality conditions for maintaining performance:
A. High filtration performance (cleaning efficiency);
B. Low air resistance;
C. Long lifespan
(2) Durable and reasonable quality conditions:
A. High pressure resistance, vibration resistance, durability, and no dust infiltration;
B. Low temperature resistance, high temperature resistance, water resistance, high-quality filter paper
C. Adhesive and rubber will not separate.
(3) Easy and lightweight loading and unloading.
