What It Is

This 2-set replacement tune-up kit (part 593260) provides spark plugs, air filters, and fuel filters for routine maintenance on Briggs & Stratton 550E/550EX series engines (09P000 family) used in Troy-Bilt push mowers and similar walk-behind models. Designed for annual service to keep small engines starting reliably and running smoothly.

Fitment & Compatibility

Must check before buying:

• Engine series: Only fits Briggs & Stratton 550E or 550EX engines with model prefix 09P000 (e.g., 09P702, 09P702-0005-F1). Not for other 500-series or larger engines.
• Deck size: Works with 21-inch–22-inch Troy-Bilt push mowers (models 11A-A2BM711, 11A-A230711, 12A-A2BU711). Confirm your mower’s model number on the deck sticker.
• OEM vs aftermarket: This is an aftermarket kit. OEM Briggs & Stratton part #593260 is the direct equivalent. Aftermarket versions typically meet or exceed OEM specs but verify gasket fit if included.
• Measurements: Spark plug gap is factory-set at 0.030 inch (check with feeler gauge). Air filter and fuel filter dimensions are standard for this engine family—no custom sizing needed.

Key Things to Know

• Quality: Aftermarket filters and plugs are generally reliable for seasonal use, but some users report slightly looser air filter fit compared to OEM. Replace every 100 hours or annually.
• Installation difficulty: Easy (30 minutes). Requires basic tools: socket wrench, spark plug gap tool, and screwdriver. No carburetor or fuel system disassembly needed.
• Common gotchas: The included spark plug may not be pre-gapped correctly—always verify 0.030-inch gap. Fuel filter arrow must point toward the carburetor. If your mower has a plastic carburetor bowl, avoid over-tightening the drain screw.
• Value: Two kits for $14.99 is cheaper than buying OEM parts separately (typically $20+ for one set). Good for households with two compatible mowers.

Should You Buy It

If you own a Troy-Bilt push mower with a Briggs & Stratton 550E/550EX engine and want an affordable, straightforward tune-up option for one or two mowers, this kit delivers reliable performance for the price. Skip it if you prefer OEM parts for warranty concerns or need a kit for a different engine series.
