593260 Air Filter Replacement for Briggs & Stratton 798452 334404 – 2PCS Lawn Mower Filters Compatible with 500E 550EX 625EX 675EXI 725EXI Series Engines – High Performance & Easy Install

What It Is

This is a two-pack of aftermarket air filters (part #593260) designed for small Briggs & Stratton engines found on walk-behind lawn mowers, pressure washers, and generators. It replaces OEM parts 798452 and 334404.

Fitment & Compatibility

Before buying, confirm your engine model series. This filter fits Briggs & Stratton 500E, 550EX, 625EX, 675EXi, and 725EXi series engines. Check your engine’s model number (stamped on the valve cover or blower housing) – it should end in a code like “Type 1234” or “Code 123456.” This filter will not fit larger engines (e.g., Intek, Vanguard) or older side-valve engines. Measure your current filter: the 593260 is roughly 4.5” wide x 2.5” tall x 1” thick. If your filter is larger or has a different mounting hole pattern, it won’t work.

Key Things to Know

• Quality: Aftermarket, not OEM. The foam pre-filter is slightly denser than factory, but still allows good airflow. Some users report a slightly tighter fit in the filter housing.
• Installation: Easy – remove the old filter, slide the new one in, and secure the cover. No tools needed. Make sure the foam pre-filter is fully seated over the paper element.
• Gotcha: This is a dual-element filter (paper + foam). If your engine only uses a paper element, this is overkill. Also, the foam pre-filter is not pre-oiled – you may need to apply a light coat of air filter oil if you mow in dusty conditions.
• Durability: Expect it to last one full mowing season (20–30 hours) under normal use. Replace earlier if you mow dry, dusty grass.

Should You Buy It

If you own a small Briggs & Stratton engine from the 500–725EXi series and want a cheap, functional replacement that’s easy to swap, this is a solid buy. It’s not OEM, but at $5.99 for two, it’s a good value for basic maintenance. Avoid if you need exact OEM fitment or run in heavy dust – a genuine Briggs filter will seal slightly better.
