Main Functions and Features Include:

1. Air Guidance: Serves as an intake channel to efficiently direct filtered, clean air from the air filter box into the engine's intake manifold.
2. Vibration Dampening and Compensation: Utilizes its flexible properties to absorb engine vibrations and compensate for movement during operation, preventing damage that could be caused by rigid connections.
3. Noise Reduction: Its corrugated or curved internal design helps to attenuate noise generated during the air intake process.
4. Environmental Resistance: Possesses excellent resistance to high and low temperatures (from -40°C to +150°C and above), engine oil vapors, and moisture.
