1. Every 12,000 to 15,000 miles (19,000 to 24,000 km): This is the most common recommendation for vehicles driven under normal conditions. Check your vehicle's owner's manual for the specific recommended interval for your car.
2. Every 6,000 to 8,000 miles (9,600 to 12,800 km): This is recommended if you drive in dusty or polluted areas, in heavy traffic, or on unpaved roads.
3. Every 30,000 miles (48,000 km) or every 2 to 3 years: If you drive mostly on highways and in clean environments, you can extend the replacement interval up to 30,000 miles or every 2 to 3 years.
4. For high-performance vehicles or those driven in extreme conditions (off-road, dusty environments, etc.): Consult the manufacturer's recommendations or consider replacing the air filter more frequently, as these vehicles can generate higher levels of contaminants.
It's important to note that these are general guidelines, and the actual replacement frequency may vary. Factors like driving habits, the type of air filter used (paper or reusable), and the overall condition of the filter can affect how often it needs to be replaced.
To ensure optimal engine performance and fuel efficiency, it's a good practice to visually inspect the air filter regularly and replace it when it shows signs of dirt, debris, or damage. Always refer to your vehicle's owner's manual for specific recommendations for your car's air filter replacement interval.
