Subaru Engine Air Filter & Maintenance

The fuel induction system sprays an air-fuel mix into the engine's combustion chamber to generate drive power. The cleanest air exiting a good air filter is the best air for the engine. The engine air filter cleans incoming air of debris, such as sand, road salt, smog, and dead insects. You want to keep debris out of the engine because they cause performance problems and damage. The engine air filter gets clogged with the filth it collects and requires replacement.

How Often Should I Replace the Engine Air Filter?

The Subaru owner's manual outlines how often an engine air filter replacement is needed. Driving conditions with poor air quality shorten the replacement interval with more frequent replacements needed. Some filters in dirty environments require replacement every 10,000 miles, while those in normal conditions might make it up to 30,000 miles. Be sure to review the details in the owner's manual and adjust replacement service based on operating conditions. We can help you stay on top of engine air filter maintenance by checking it when you get oil changes at Serra Subaru Champaign County.
