Change Car Air Filter Subaru XV Crosstrek

All the oxygen the engine needs passes through the air filter. Dust is abrasive and can cause premature engine wear. A clogged filter also causes increased fuel consumption and reduced performance.

Generally replace every 20,000–40,000 km or every 1–2 years. In dusty environments or for frequent off-road use, replace more frequently.

Difficulty level 1/5: very easy. The air filter is normally very accessible. The whole operation takes 5–10 minutes and requires no tools in most cases.
