What It Is

This is a replacement air filter set for Briggs & Stratton 500EX, 550EX, 675EXi, and 725EXi engines. It includes both a paper filter and a foam pre-filter, designed to keep dust and debris out of small engines on push mowers like Troy-Bilt TB110, TB200, and TB230.

Fitment & Compatibility

Check your engine model number, not just mower brand. This filter fits Briggs & Stratton engines with model numbers 4247, 5432, 5432k, 09P00, and 09P702. It replaces OEM part numbers 593260, 798452, and 334404. The paper filter measures roughly 4.5 x 3.5 x 1.5 inches; the foam pre-filter is about 3.5 x 2.5 x 1 inches. Not compatible with larger Briggs engines (e.g., 850EX, 1000 series) or non-Briggs engines. Always remove your old filter and compare shape and mounting holes before buying.

Key Things to Know

• Two-piece design – The foam pre-filter should be cleaned and oiled (use foam filter oil) before installation; the paper filter is dry and disposable.
• Easy install – No tools required. Just unclip the air filter cover, swap the old set, and re-clip. Takes under 2 minutes.
• Common gotcha – Some aftermarket foam pre-filters are slightly thicker than OEM. If it’s too tight, you can trim the foam with scissors to fit the housing.
• Not a universal fit – Even within the listed engine families, slight housing variations exist. If your old filter has a different shape or a rubber gasket, this set likely won’t work.

Should You Buy It

If you own a Briggs & Stratton 500EX–725EXi engine (especially on a Troy-Bilt TB series mower) and need a budget-friendly, well-reviewed replacement, this set is a solid choice. It’s cheap, easy to swap, and includes both the paper and foam elements your engine needs. Skip it if your engine isn’t in the listed model range or if you prefer an exact OEM part.
