Power Performance

What It Is

The Power Performance air filter (likely a foam or paper element) is a direct replacement for small engine air filtration systems, commonly used in walk-behind lawn mowers, riding tractors, and zero-turn mowers with engines like Briggs & Stratton, Kohler, or Kawasaki.

Fitment & Compatibility

Before buying, verify these three things:

• Engine model number: Check the engine’s ID tag (usually stamped on the blower housing or valve cover). The Power Performance filter fits many 7000–8000 series Briggs & Stratton engines and select Kohler Courage/Command series.
• Dimensions: Measure your current filter’s length, width, and height (typical sizes: ~5x3x1.5 inches). The product listing should include these; if not, compare against OEM part numbers like Briggs 793870 or Kohler 12-050-01-S.
• Air box type: This is a pre-filter or primary filter, not a cartridge. Ensure your mower uses a flat, rectangular foam or paper element (not a round or pleated cartridge). Aftermarket compatibility is generally good, but avoid if your engine requires a specific OEM-only gasket or pre-filter.

Key Things to Know

• Quality: At $6.36, it’s a budget aftermarket option. Expect basic filtration—fine for residential mowing, but not for heavy dust or commercial use. Some users report slightly thinner foam than OEM.
• Installation: Tool-free—remove the air filter cover, swap the old filter, and reinstall. Takes 2 minutes. No oiling needed for foam pre-filters (check if yours is dry or oiled).
• Common gotcha: The filter may be slightly undersized in thickness (1/8 inch short). If your air box has a tight seal, this can allow unfiltered air in. Stack a second filter or add a foam gasket if gaps appear.
• Durability: Expect 1–2 seasons of typical use before needing replacement. Washable foam versions can be cleaned with soap and water, but paper versions are disposable.

Should You Buy It

If you need a cheap, quick replacement for a common small engine air filter and your mower doesn’t operate in heavy dust or professional conditions, this is a fine budget pick. For high-horsepower commercial mowers or engines with tight air box tolerances, spend a few dollars more on an OEM filter.
