2 Pack 796031 Air Filter Replace for BS 992376 590825 591334 594201 OEM Air Cleaner Cartridge with 797704 Pre Filter Fits Lawn Mower Air Cleaner Element

What It Is

This is a 2-pack aftermarket air filter set (part 796031) with a pre-filter (797704), designed to replace Briggs & Stratton OEM filters 992376, 590825, 591334, and 594201. It fits most walk-behind lawn mowers, zero-turn mowers, and small engines using Briggs & Stratton single-cylinder engines, typically 450–550 series.

Fitment & Compatibility

• Check your engine model: Works with Briggs & Stratton engines using these OEM part numbers. Look for the engine model number (e.g., 12H702) stamped on the valve cover or blower housing.
• Not universal: Does not fit Kohler, Honda, Kawasaki, or other brands—only B&S engines with the rectangular air filter housing.
• Dimensions: Filter is roughly 6.5" x 4.5" x 1.5"; pre-filter is foam. Measure your current filter to confirm.
• OEM vs aftermarket: This is a non-OEM replacement. Quality is good, but slightly looser fit reported on some older housings—check seal after installation.

Key Things to Know

• Installation: Easy—swap the old filter and pre-filter, no tools needed. Ensure the pre-filter sits flat under the cover.
• Quality: Foam pre-filter is less dense than OEM, but the paper element is fine. Replace every 25–50 hours or once per season.
• Gotcha: If your housing has a small tab or clip, the pre-filter may not align perfectly—trim with scissors if needed.
• Value: 2-pack for under $10 is cheaper than a single OEM filter. Good for multiple mowers or bulk storage.

Should You Buy It

Buy if you have a Briggs & Stratton engine needing filter 796031 and want a budget-friendly 2-pack for routine maintenance. Skip if you prefer OEM fitment or have a non-B&S engine—measure first to avoid returns.
