Lawn Mower Tune Up Kit – 593260 Air Filter + Spark Plug Compatible with Troy-Bilt TB110 TB115 TB200 TB230 TB330 TB370 – Fits 593260 Engines

What It Is

This tune-up kit bundles a pre-gapped spark plug and an air filter for Troy-Bilt push mowers. It’s designed for routine annual maintenance to restore starting ease and cutting performance on residential mowers with 593260-series engines.

Fitment & Compatibility

Check your model number first. This kit fits Troy-Bilt TB110, TB115, TB200, TB230, TB330, and TB370 mowers. The “593260” in the title refers to the engine family (typically a Briggs & Stratton 593260), not the mower model. Confirm your mower’s engine type—look for a sticker on the engine shroud or under the rear flap. If you have a different Troy-Bilt model (e.g., TB240, TB280) or a non-Troy-Bilt mower with the same engine, the spark plug and air filter may still be compatible, but verify the air filter shape and plug gap (0.030” is standard for these engines). Measure your old air filter: it should be roughly 3” x 2” rectangular foam. This is an aftermarket kit, not OEM Troy-Bilt, but uses equivalent spec parts.

Key Things to Know

• Quality is adequate for the price. The spark plug is a standard copper-core (likely equivalent to a Champion RJ19LM or J19LM). Replace annually—it won’t last multiple seasons like an iridium plug.
• Installation is easy. Takes 10 minutes: remove the old air filter (no tools), unscrew the old plug (5/8” socket), gap the new plug to 0.030” (use a feeler gauge—don’t skip this), and reinstall.
• Common gotcha: The foam air filter may be slightly thicker than the OEM part. If it feels too tight in the housing, trim it slightly with scissors; if too loose, it won’t seal properly and dirt can enter. Check fit before closing the cover.
• Not a full tune-up kit. This includes only air filter and spark plug. You may still need fresh oil and fuel stabilizer for a complete service.

Should You Buy It

If you own a Troy-Bilt TB110–TB370 with a 593260 engine and just want a cheap, fast way to refresh your mower for the season, this kit works fine. It’s not the highest quality—expect to replace again next year—but at $7.99, it’s a solid value for basic DIY maintenance. Skip it if you need OEM parts for warranty compliance or want a longer-lasting spark plug.
