593260 Air Filter with Pre Filter and Spark Plug Fits for B&S 725EX 625EX 575EX 550EX 525EXI Engines, Air Filter Parts for Toro Recycler 22 and Troy Bilt Lawn Mower (2 Pack)

What It Is

This is a 2-pack replacement air filter with pre-filter and a spark plug, designed for small Briggs & Stratton engines (725EX, 625EX, 575EX, 550EX, 525EXI) commonly found on Toro Recycler 22 and Troy-Bilt walk-behind mowers. It keeps dirt out of the carburetor and provides a fresh spark plug for reliable starting.

Fitment & Compatibility

Before buying, check your engine’s model number (stamped on the blower housing or under the fuel tank). This part fits B&S 725EX, 625EX, 575EX, 550EX, and 525EXI engines. It’s also listed for Toro Recycler 22 (models 20333, 20334, 20340, 20341, 20342, 20370, 20371) and several Troy-Bilt mowers. Measure your existing air filter—this one is approximately 4.5 x 3.5 x 1.5 inches. The spark plug is a standard B&S 796112S (replaces 491055, 693051, 796112). If your engine uses a different plug gap (usually 0.030”), confirm it matches your manual. Not compatible with Honda, Kohler, or Kawasaki engines.

Key Things to Know

• Quality vs OEM: This aftermarket filter foam is slightly less dense than genuine B&S, but still effective for normal residential use. The spark plug is a solid copper-core replacement—fine for seasonal mowing, but not for heavy commercial use.
• Installation difficulty: Very easy—no tools needed for the air filter (just unclip the cover, swap foam and paper, re-clip). The spark plug requires a 5/8” socket wrench; gap it to 0.030” before installing.
• Common gotcha: The pre-filter (foam) must be oiled lightly before use—dry foam lets fine dust through. Use a few drops of motor oil, squeeze out excess, then install. Skipping this reduces filter life.
• Pack includes two full sets: Two air filters, two pre-filters, and two spark plugs. Good for two changes or one mower plus a spare.

Should You Buy It

If you own a Toro Recycler 22 or Troy-Bilt with a compatible B&S engine and want a budget-friendly, reliable replacement for routine maintenance (every 25–50 hours), this is a solid buy. It’s not for commercial-grade durability, but for home lawns, the value and convenience of a 2-pack with a spark plug make it a smart choice.
