Extended Life Series 2 Pack of Air Filter Compatible with 792105 276890 4163205 4163206 44H777 Foam Pre-cleaner (Pack of 2)

What It Is

This is a 2-pack of air filters with foam pre-cleaners, designed to replace OEM part numbers 792105, 276890, 4163205, 4163206, and 44H777. It’s intended for small engines in lawn mowers, tractors, and zero-turn mowers that use a paper filter with a separate foam pre-filter layer.

Fitment & Compatibility

Before buying, check your engine’s filter housing. This set fits many Briggs & Stratton, Kohler, and Kawasaki engines found on brands like John Deere, Husqvarna, Craftsman, and Toro. Measure your old filter: the paper element is roughly 4.5” x 2.5” x 1.5” and the foam pre-cleaner is about 4.5” x 2.5” x 0.75”. Verify the OEM part numbers match (792105, 276890, 4163205, 4163206, 44H777) – these are common on 500cc to 700cc engines. If your engine uses a single foam-only filter or a different shape, this won’t fit. Also confirm the pre-cleaner slides over the paper filter snugly; some housings require a specific orientation.

Key Things to Know

• Quality vs OEM: This aftermarket filter is comparable to OEM in filtration, but the foam pre-cleaner may be slightly less dense. It’s fine for residential use; heavy-duty commercial operators might prefer OEM.
• Installation: Easy – remove old filter, clean the housing, slide the foam pre-cleaner over the new paper filter, and insert. No tools needed. The foam should be oiled lightly (use filter oil, not engine oil) for best dirt capture.
• Common Gotcha: The foam pre-cleaner can be tight on the paper filter. If it’s too snug, trim the foam slightly with scissors. Never run the engine with the foam missing – it protects the paper element from large debris.
• Maintenance: Wash the foam pre-cleaner in soapy water every 25 hours, re-oil, and replace the paper filter yearly or after 100 hours.

Should You Buy It

If you need a reliable, budget-friendly replacement for a common filter set and don’t mind a slightly less dense pre-cleaner, this 2-pack is a solid value for residential mowers. It’s not for commercial use or engines with non-standard filter shapes.
