What does an air filter do?

An air filter helps your engine run smoothly. It does this by intercepting tiny particles like dust and dirt before they reach your engine. This helps your engine run efficiently, as these particles can cause damage if not trapped. A clean air filter also ensures the optimal amount of clean air mixes with your fuel. This enhances engine performance and fuel efficiency.

How often should you replace your air filter?

How often you change your air filter depends on your car. Usually, manufacturers recommend replacing them in an annual service or every 12,000-15,000 miles—whichever comes first. If you’re unsure, check your vehicle’s manual for specific recommendations. Regular replacement helps keep your engine running smoothly.

Signs you need to replace the air filter

  • 12 months or 12,000-15,000 miles (whichever sooner) since your last change.
  • Air flow issues
  • Reduced fuel efficiency
