Large filtration area: Designed with a large filtration area, it can increase air flow while maintaining good filtration effect, improving engine performance and fuel efficiency. 2. Low flow resistance: The resistance of the air filter should be as low as possible to ensure that air can enter the engine quickly and smoothly, improving the engine's response speed and power output. 3. Sturdy structure: High quality air filters typically use durable plastic or metal frames that can withstand high temperatures and vibrations inside the engine compartment, ensuring long-term use without deformation. 4. Easy to clean and maintain: Some air filters are reusable and designed with convenient disassembly and cleaning structures for easy maintenance. 5. Sealing: High quality rubber sealing rings are used to ensure a good seal between the air filter and the intake manifold, preventing unfiltered air from entering the engine. 6. Long lifespan: High quality air filters are designed to have a long lifespan, maintaining good filtration performance for a longer period of time and reducing replacement frequency. 7. Environmental adaptability: Adapt to various climate and environmental conditions, whether it is humid tropical climate or dry desert environment, and can maintain stable working performance
