Checking your car’s air filter regularly is crucial for maintaining engine performance and fuel efficiency. Generally, you should inspect your air filter every 12,000 to 15,000 miles or at least once a year, but this can vary based on driving conditions and vehicle type.

Why is Checking Your Car’s Air Filter Important?

The air filter in your car plays a vital role in ensuring that clean air reaches the engine. A clean air filter improves engine performance and fuel efficiency, while a dirty or clogged filter can lead to reduced power and increased emissions. Regular checks help prevent these issues and extend your vehicle’s lifespan.
