593260 Lawn Mower Air Filter 798452 334404 Air Filter, Replacement Accessories for Most Lawn Mowers 500, 500E, 550E, 500EX, 550EX, 625E, 675, 625EX, 675EX, 675EXI, 725EXI Series Engines (2PCS)

What It Is

This is a replacement foam air filter designed for select Briggs & Stratton 500, 550, 600, 625, 675, and 725 Series engines. It traps dirt and debris before they enter the carburetor, critical for maintaining engine performance in push mowers, riders, and tractors using these engines.

Fitment & Compatibility

• Primary fit: Briggs & Stratton 500E, 550E, 500EX, 550EX, 625E, 675, 625EX, 675EX, 675EXI, 725EXI Series engines.
• OEM cross-references: 593260, 798452, 334404. If your current filter has any of these numbers stamped on it, this is a direct drop-in.
• What to measure: Filter dimensions are approximately 4.5" x 3" x 0.75" (L x W x H). Measure your current filter’s length, width, and thickness before ordering—some 500/550 series use a slightly different shape.
• Not compatible with: Intek, Vanguard, or single-cylinder OHV engines with plastic housing filters. Verify your engine’s model number (e.g., “12A-…” or “1P65…” printed on the valve cover or blower housing).

Key Things to Know

• Quality: Basic foam construction—works fine for residential use, but may degrade faster than OEM under heavy dust or frequent mowing. Replace every 25 hours or once per season.
• Installation: Tool-free—remove old filter, clean the housing with a rag, press in the new filter. Ensure it seats flat; gaps cause dirt bypass.
• Common gotcha: This filter is dry foam, not oiled. Do not apply oil unless your engine manual specifies it. Oiling a dry foam filter can restrict airflow and cause rich running.
• Pack of 2: You get two filters for $4.90. Keep one as a spare or replace mid-season if mowing dusty conditions.

Should You Buy It

If you have a Briggs 500–725 Series engine and want a low-cost, no-hassle replacement for basic home lawn care, this is a solid budget pick. It’s not heavy-duty enough for commercial use or extreme dust, but for a single mower cut once a week, it’s more than adequate.
