Briggs & Stratton

What It Is

This is a genuine Briggs & Stratton replacement air filter, designed for use in Briggs & Stratton engines commonly found on walk-behind mowers, riding mowers, and small utility equipment. It ensures clean airflow into the carburetor for proper fuel combustion and engine performance.

Fitment & Compatibility

Check your engine’s model number (stamped on the valve cover or near the muffler) and confirm it matches Briggs & Stratton air filter part numbers 492932, 793619, or 5095 (cross-check with your manual). This filter fits most Briggs engines with a rectangular or foam-style air box, common on Series 450e, 500e, 625e, and 725e engines. Measure the filter opening: it’s roughly 3.5 x 3.5 inches with a 1-inch depth. It is an OEM part, so it’s a direct replacement for the original filter. Not compatible with Kohler, Honda, or Kawasaki engines.

Key Things to Know

• Quality: Genuine Briggs & Stratton part—better foam density and fit than most aftermarket filters. Expect longer service life.
• Installation: Easy, no tools needed. Remove the air filter cover, swap out the old filter, and reattach the cover. Takes under 2 minutes.
• Common gotcha: Some engines use a pre-filter or foam wrap; this is a dry, pleated paper filter—do not oil it. Also, check that the filter housing gasket isn’t cracked or missing before installing.
• Maintenance: Replace every 25 hours or once per season, sooner if you mow in dusty conditions. A dirty filter reduces power and increases fuel consumption.

Should You Buy It

Yes, if you have a Briggs & Stratton engine in the common 450e–725e range and want a hassle-free, guaranteed fit. The $11.99 price is fair for an OEM part that won’t let you down, and the 5.0-star rating reflects consistent reliability. Skip it only if you need a foam or oiled filter for heavy-dust environments.
