593260 Air Filter Set Spark Plug Compatiable with Troy-Bilt TB110 TB115 TB200 TB230 TB330 TB370 Walk Behind Lawn Mower

What It Is

This is a maintenance kit containing an air filter, spark plug, and often a fuel filter, designed for Troy-Bilt walk-behind mowers in the TB110 through TB370 series. It replaces the engine’s consumable wear items to keep the engine running clean and firing reliably.

Fitment & Compatibility

• Check your model number: This kit fits Troy-Bilt TB110, TB115, TB200, TB230, TB330, and TB370 models. Look for the model number on a sticker under the seat or on the mower deck.
• Engine type matters: It’s meant for engines in these Troy-Bilt models (typically Briggs & Stratton or similar single-cylinder OHV engines). If your mower uses a different engine brand (e.g., Honda), it likely won’t fit.
• OEM vs aftermarket: This is an aftermarket replacement, not genuine Troy-Bilt OEM. That’s fine for routine maintenance, but check the included spark plug gap—aftermarket plugs sometimes need you to gap them to 0.030” (0.76 mm) manually.
• Measure the air filter: The paper filter element is roughly 3.5” x 2.5” x 1.5”. If your current filter is a different shape or size, this kit won’t work.

Key Things to Know

• Installation is easy – No special tools beyond a socket wrench for the spark plug and a screwdriver for the air filter cover. Takes about 10 minutes.
• Fuel filter included – Most kits include a small inline fuel filter. If your mower doesn’t have one, you can skip it, but installing it is a good idea if your model supports it.
• Check spark plug gap before installing – The included plug may be pre-gapped, but verify with a feeler gauge. Wrong gap causes misfires or hard starting.
• Not for zero-turn or riding mowers – This kit is strictly for walk-behind push mowers in the TB series. Larger tractors use different parts.

Should You Buy It

If you own a Troy-Bilt TB110–TB370 walk-behind mower and want an affordable, complete maintenance set, this kit is a solid choice. It’s cheap, covers the three most common wear items, and saves you from buying them separately. Just verify your model number and gap the plug—then you’re set for the season.
