Air filter

In Turkish: Hava filtresi

In short

An air filter stops dust and particles in the intake air, protecting the cylinder, piston and rings from wear.

Paper filter: not cleaned; replaced at set intervals.
Foam filter: washed and re-oiled with filter oil, then reused.
Cotton (performance) filter: washed and re-oiled with its own oil.

A clogged air filter enriches the mixture, causing power loss, more spark plug fouling and higher fuel use. On bikes used in dusty conditions, check the filter more often than the manual's interval.
