What are the potential hazards of not replacing the air filter for 30,000 kilometers?

[NathanRose]

Here are the potential hazards of not replacing the air filter for 30,000 kilometers: 1. The air filter cannot effectively remove suspended particles from the air, leading to accelerated engine wear and carbon buildup, shortening the engine's lifespan. In severe cases, it may even cause "cylinder scoring." 2. If the air filter is not replaced for a long time, it loses its intended function, directly affecting the air quality inside the cabin. This small space, where you spend at least 2 hours daily, can become poorly ventilated. Prolonged exposure to such conditions may lead to health issues. Additional Information: The typical replacement cycle for an air filter is 10,000-20,000 kilometers, but this can vary significantly depending on driving conditions. In poor environments, earlier replacement may be necessary.
