593260 Tool Parts Oval Air Filter with Spark Plug for Troy-Bilt TB110 TB115 TB200 TB230 TB330 TB370 Walk-Behind Lawn Mower : Garden & Outdoor

What It Is

This is a combined replacement air filter and spark plug kit for Troy-Bilt walk-behind lawn mowers. It keeps debris out of the engine and provides the spark needed for ignition, all in one convenient package.

Fitment & Compatibility

Before buying, verify your mower’s model number (e.g., TB110, TB115, TB200, TB230, TB330, TB370). This kit fits those specific Troy-Bilt models but not all Troy-Bilt mowers—check your engine’s model plate (usually near the spark plug or under the fuel tank). The air filter is oval-shaped, not round, so measure your old filter’s outer dimensions (approx. 5” x 3.5”) if unsure. The spark plug is a standard 14mm thread with a 0.030” gap (pre-gapped, but always verify). This is an OEM-style replacement, not a universal fit.

Key Things to Know

• Quality: OEM-grade materials; the filter uses pleated paper and foam, the plug is copper-core. Expect 50–100 hours of use per filter/plug set.
• Installation: Easy—no tools for the filter (just remove the cover, swap), but use a spark plug wrench for the plug. Torque to 20 ft-lbs (hand-tight + 1/4 turn).
• Common gotcha: The spark plug gap is pre-set, but always check with a feeler gauge (0.030”)—it can shift during shipping. Also, the filter must be seated fully to avoid air leaks; press down until it clicks.
• Savings: Buying this kit costs less than separate OEM filter + plug purchases, and you get one part number for both.

Should You Buy It

If you own a compatible Troy-Bilt TB-series mower and want a quick, drop-in replacement that restores performance and extends engine life, this kit is a solid choice. It’s ideal for DIY homeowners who change both filter and plug annually—saves time and money over buying separate OEM parts.
