This is a replacement air filter 3-piece set for Honda GX25 series 4-stroke petrol engines, keeping your lawn mower or brushcutter running cleanly and efficiently.
Compatible with Honda GX25, GX25N, GX25NT, HHT25S, UMK425, ULT425, and UMS425 models. Each filter replaces OEM part number 17211-Z0H-000. The set includes 3 individual filters, so you’ll have spares on hand for regular maintenance cycles.
Clean air filters are essential for engine performance and fuel efficiency. Clogged filters force your engine to work harder, reducing cutting power and increasing fuel consumption. Regular replacement extends engine life and ensures consistent operation during the busy mowing season.
Installation is straightforward on most Honda small engine equipment. Remove the old filter housing cover, swap out the worn filter, and secure the new one in place—no special tools required.
