Air filters, are an essential requirements in the efficient combustion of air/fuel mixture, and the smooth running of an engine.

Without a functional air filter media, ambient air, which is supposed to be cleanly filtered, before it gets to the throttle body assembly, via the intake manifold, would either caused a fuel rich problem, or some driveability issues.

Good, quality air filters, helps filters the air, and males it suitable for use during combustion.

Bad filters allows unfiltered air gained access into the combustion chambers, and cause cylinder scouring.
Below was a Prius I had worked on some days back.

After completing the oil change, I realized air filter was as below.

Always replaced those filters, as at when due. It saves you a lot.


PS: car is about 50,000km
