796031 Air Filter with 797704 Pre Filter Replacement for Briggs and Stratton 594201 591334, Fits John Deere D100 D110 D125 D130 MIU13038 GY21435 MIU13963 MIU14395, Husqvarna YTH22V46 Lawn Mower

What It Is

This is a two-piece air filter set (main filter #796031 plus foam pre-filter #797704) designed for Briggs & Stratton engines commonly used on riding mowers like John Deere D100-D130 and Husqvarna YTH22V46. It traps dirt and debris before they enter the carburetor, ensuring clean airflow for reliable engine performance.

Fitment & Compatibility

• OEM cross-references: Briggs & Stratton 594201, 591334; John Deere MIU13038, GY21435, MIU13963, MIU14395.
• Machine fit: John Deere D100, D110, D125, D130; Husqvarna YTH22V46. Also fits many other Briggs-powered riders—check your engine model (e.g., 31C707, 31P977) on the valve cover or shroud.
• Physical check: Measure the filter base diameter (approx. 5.5” outer) and height (2.25”). If your old filter matches these dimensions, this set will work.
• Aftermarket vs OEM: This is a third-party replacement, not genuine Briggs or Deere. It’s a direct fit for the listed cross-references but may vary slightly in foam density or paper pleat count.

Key Things to Know

• Installation is tool-free: Remove the wing nut, swap the old filter and pre-filter, and re-tighten. No special tools needed.
• Don’t skip the pre-filter: The foam wrap catches larger debris and extends the life of the paper filter. Clean it with soapy water (never oil) every 25 hours.
• Check for debris in the housing: Before installing, vacuum out any grass or dirt that fell into the air box—common on riding mowers.
• Not for zero-turns or push mowers: This is specifically for Briggs V-twin engines on tractors. Confirm your engine model before buying.

Should You Buy It

If you own a John Deere D100–D130 or Husqvarna YTH22V46 and need a budget-friendly replacement for the Briggs 594201/591334, this set works well. It’s a simple swap, and the 4.5-star rating suggests reliable fit and performance for the price. Just verify your engine model and filter dimensions first.
