Briggs & Stratton

What It Is

This is a genuine Briggs & Stratton replacement air filter for small engines in lawn mowers, tractors, and zero-turn mowers. It captures dirt and debris before they enter the carburetor, protecting engine performance and longevity.

Fitment & Compatibility

• Check your engine model number: Look for a stamped code on the engine shroud (near the spark plug) or on the valve cover. This filter fits many Briggs engines with a 2.5–6.5 HP range, typically Intek, Quattro, and Classic series.
• Verify OEM part number: Cross-reference with your original filter’s part number. Common matches include Briggs #491588, #492932, and #593225. Not all aftermarket filters are identical; this is OEM, so it matches factory specs.
• Measure the filter housing: The filter is roughly 3.5" x 2.5" x 1.5". If your current filter is bigger or smaller, it won’t fit.
• Deck size isn’t relevant—only the engine matters.

Key Things to Know

• Installation is 5 minutes: No tools required—just unclip the old filter, pop in the new one, and re-secure the cover.
• Replace every season or 25 hours of use: A dirty filter restricts airflow, causing hard starts, rough idle, and power loss.
• Avoid oiled foam alternatives: This is a dry paper filter. Don’t oil it or clean it with water; replace it instead.
• Common gotcha: Some generic “fits all” filters are slightly undersized and let unfiltered air bypass. Stick with OEM for a tight seal.

Should You Buy It

Yes, if you have a compatible Briggs engine and want a no-hassle, direct-fit filter that maintains factory airflow. It’s a cheap, quick fix for poor performance or black smoke from a clogged filter. Skip it if your engine isn’t on the compatibility list—you’ll waste time and money.
