Your Subaru likely comes with two types of air filters.

Engine Air Filter: The engine air filter prevents dirt, dust and debris from making its way into your Subaru’s engine. At the same time, the air filter lets in the appropriate amount of air into your engine, allowing it to operate properly. Depending on your typical driving conditions, the lifespan of your air filter may vary. However, it is typically recommended to have the engine air filter replaced approximately every 48,000 km.

Cabin Air Filter: The cabin air filter helps to filter the air that comes through your Subaru’s heating and cooling systems, leaving you with clean air to breathe. Over time this filter can get clogged, so it should be replaced periodically.

How do I know when I need new air filters?

• Engine air filter: you experience a decrease in fuel efficiency, your engine makes abnormal sounds, or if you see black smoke coming from your exhaust
• Cabin air filter: you detect a strange smell when your air conditioning or heating system is on, or if it’s airflow is weaker than usual

If you observe any of these problems in your Subaru, it may be time to replace your air filters. Ready for an appointment? Schedule an appointment today.
