A clean air filter improves performance and fuel economy.

3 min read3 sections

1What It Does

The engine air filter prevents dust, dirt, and debris from entering your engine. A clogged filter restricts airflow, reducing power and fuel economy.

2When to Replace

Most filters need replacement every 20,000-40,000 km, but dusty conditions shorten this. Check it every oil change.

3How to Check

Open the air filter box (usually has clips or screws), remove the filter, and hold it up to light. If you can't see light through it, replace it.

Pro Tip: This is one of the easiest DIY jobs. Filters cost $15-30 and take 5 minutes to replace.
