593260 Air Filter Replaces 798452 334404, 2Pcs Professional Lawn Mower Replacement Air Filters for 550E 09P702 500EX 550EX 625 575EX 09P00 5432 5432K 4247 Series Engine

What It Is

This is a two-pack of aftermarket air filters designed for small engines in walk-behind lawn mowers, specifically those using Briggs & Stratton’s 500E, 550EX, 575EX, 625, and similar Series engines. The foam element traps dirt and debris before it enters the carburetor, protecting engine life.

Fitment & Compatibility

Before buying, verify your engine’s model number (stamped on the valve cover or above the spark plug). This filter replaces OEM part numbers 593260, 798452, and 334404. It fits Briggs & Stratton engines in the 500E, 09P702, 500EX, 550EX, 625, 575EX, 09P00, 5432, 5432K, and 4247 Series. It does not fit all Briggs engines—avoid using it on Intek, Vanguard, or larger twin-cylinder models. Measure your existing filter: this is a foam, rectangular filter roughly 3.5” x 2.5” x 1.5”. If your filter is paper or a different shape, it won’t work.

Key Things to Know

• Quality: This is an aftermarket filter, not OEM Briggs & Stratton. Users report it fits snugly and filters well, but the foam may be slightly denser than the original. Rinse with warm soapy water and re-oil lightly if your mower runs in dusty conditions.
• Installation: Takes 30 seconds—remove the air filter cover, swap the old filter, and snap the cover back on. No tools needed.
• Common gotcha: Some mowers use a separate pre-filter or foam wrap; this kit includes only the main filter element. Check if your mower needs both.
• Value: At ~$2.50 per filter, it’s a fraction of the cost of two OEM filters. Good for seasonal replacement or as a backup.

Should You Buy It

If you have a small Briggs & Stratton engine (500-625 Series) and want a cheap, reliable replacement that works fine for typical homeowner mowing, this two-pack is a solid buy. Skip it if you need an exact OEM fit for a commercial mower or if your engine uses a paper filter—this is foam only.
