Engine Air Filter: what it does & when to replace it
The engine air filter keeps dust, pollen, and debris out of the intake so only clean air reaches the combustion chamber. A clogged filter restricts airflow, which can reduce fuel economy and acceleration. Most are replaced every 20,000–30,000 km, sooner in dusty conditions. A quick check: hold it up to light — if little passes through, replace it. This is one of the simplest maintenance tasks; the filter usually sits in an airbox under a few clips with no tools required, making it a true beginner DIY job.
DIY difficulty: Very easy DIY (5–10 minutes, no tools). Always confirm the correct part for your exact build by VIN before buying.
