Foam Air Filter A226000740

This is an OEM sourced replacement part used on Shindaiwa trimmers. Its purpose is to filter out dust and debris from contaminating the carburetor and engine. When replacing the filter you can open the package in comes in and put a bit of two cycle oil in the bag and let it absorb into the filter. Then remove it from the bag and squeeze it with a paper towel to remove the excess oil. To replace this filter no special tools are needed. Simply remove the cover and replace the filter element.
