593260 Air Filter with Pre-Filter & Spark Plug Compatible with Briggs & Stratton 500EX/550EX/575EX/625EX/725EXI, Toro Recycler 22, Troy-Bilt TB110/TB200/TB230 Lawn Mowers-2Pack

What It Is

This 2-pack kit includes an air filter, pre-filter, and spark plug for small engines in push mowers like the Briggs & Stratton 500EX/550EX/575EX/625EX/725EXI series, Toro Recycler 22, and Troy-Bilt TB110/TB200/TB230. It’s a routine maintenance set for replacing wear items that keep the engine breathing clean and firing reliably.

Fitment & Compatibility

Before buying, verify your mower’s engine model number (e.g., 500EX, 550EX) – it’s stamped on the engine shroud near the spark plug or air filter cover. This kit fits Briggs & Stratton engines with a horizontal shaft and standard 0.030” spark plug gap. It’s aftermarket, not OEM, so check that your existing air filter and pre-filter measure roughly 3.5” x 2.5” (the spark plug is a standard J19LM or equivalent). It won’t fit vertical shaft engines, larger engines (e.g., 850EX), or mowers with a different air filter housing (e.g., some Honda or Kohler models). Toro Recycler 22 models from 2010+ and Troy-Bilt TB110/TB200/TB230 (with Briggs engines) are confirmed matches.

Key Things to Know

• Quality vs. OEM: The air filter and pre-filter are dense foam and paper – adequate for seasonal use, but the pre-filter may be slightly less durable than Briggs OEM parts. Replace every 25-50 hours or annually.
• Installation is easy: No tools needed for the air filter (just remove the cover, swap the filter and pre-filter). The spark plug requires a 5/8” socket and a torque wrench (recommended 15-20 ft-lbs). Gap the plug to 0.030” before installing.
• Common gotcha: The pre-filter is foam – oil it lightly with air filter oil (or motor oil) before installing. A dry pre-filter lets dirt through. The spark plug may not come pre-gapped – always check.
• 2-pack value: You get two complete sets (filter + pre-filter + plug) – handy for two mowers or one mower with a spare set. The plug is a copper-core, so expect 50-100 hours of life.

Should You Buy It

If you own a Briggs 500-725EX series mower (Toro Recycler 22, Troy-Bilt TB110/200/230) and want a cheap, no-fuss maintenance bundle, this is a solid choice for the price. It’s not premium OEM quality, but for $10 you get two full service sets – perfect for budget-conscious DIYers who change filters and plugs annually. Skip it if you need exact OEM fitment or have a non-Briggs engine.
