The GX110 air filter is an oval paper filter cartridge for mowers and brush cutters. The yellow pleated paper sits inside an oval metal flanged end plate, with one center port, and it drops into the oval air housing as is. GX110 and GX120 engines share this filter, so it is a direct swap. The pleats hold plenty of dust, and the element is due for replacement when the yellow paper goes dark and the pleats no longer spring back. Before fitting, remove the housing cover, wipe the inner walls with a dry cloth, and check the flange sealing surface. Do not wash the paper element in water, and if you need to clean it, blow dust off gently with compressed air. GX140 and GX160 engines also use oval filters, but do not assume they all fit. Compare the old part before ordering, or send a photo to confirm.

 FAQ 

Q1: Can I wash the GX110 air filter in water?

No. This is a paper element, and water soaks the pleated media and warps it as it dries. Wipe the housing dry and replace the element when the paper is clogged.

Q2: Which engines does this oval air filter fit?

GX110 and GX120 engines share this filter. GX140 and GX160 engines also use oval filters, so compare the old element or send a photo before ordering to make sure it matches.

Q3: How do I know when it is time to replace it?

Look at the paper. When it has gone dark with dust and the pleats are crushed or torn, fit a new element. In dusty conditions, check more often.
