What Does an Air Filter Do?
The air filter protects your engine and affects how it runs. A Cranbourne West specialist explains.
What it is & what it does
The engine air filter cleans the air entering the engine, stopping dust and grit from causing wear. A clean filter lets the engine breathe; a clogged one restricts airflow, hurting power and economy.
It’s a cheap, routine service item replaced at intervals (sooner in dusty conditions).
Signs of trouble & how we help
A very dirty air filter can cause sluggishness and slightly worse economy. It’s checked and replaced as part of servicing — cheap protection for an expensive engine.
We check and replace the air filter at the right interval, sooner if you drive in dusty conditions.
