How often do you really need to change car air filter?

Why Change the Air Filter?
The air filter in your car plays a crucial role in keeping the engine running efficiently. It traps dirt, dust, and other airborne particles that could otherwise enter the engine and cause damage. A clogged or dirty air filter can reduce airflow, leading to decreased fuel efficiency, reduced engine power, and even increased emissions.
Factors That Affect Air Filter Replacement

- Engine Performance: If you notice a decrease in engine power, reduced fuel efficiency, or increased engine noise, it may be a sign that the air filter needs to be replaced.
- Manufacturer Recommendations: Always refer to your vehicle's owner's manual for the manufacturer's recommended air filter replacement schedule, as this may differ from the general guidelines.li>
By keeping a close eye on your air filter and replacing it as needed, you can help ensure your car's engine runs smoothly and efficiently, while also extending the life of your vehicle.
