Ensure that the air screen is also cleaned regularly to prevent buildup of dust and debris – use a wire brush to clean the gauze. An unclean mesh will also leave your engine more susceptible to overheating. Locate the filter (usually next to your engine block) and open the housing, clear out any debris before removing the screen and surrounding spacers. Use kerosene or any recommended lubricant to clean the filter’s foam element (engine oil can also be used) and allow excess fluid to drop off. Leave the filter overnight to dry before replacing it. If you’re unable to clean the filter, replace it with a new one. Squeeze the element the next day to remove excess oil as this can attract dust.
Proceed to reassemble the element within the filter and insert back into its housing. Fasten the screen.
