698369 Foam Air Filter For Briggs & Stratton Lawn Mower 698369 4216 5088 5099 MTD 490-200-0011-(2PCS)

What It Is

This is a two-pack of foam air filter elements designed for small engines, primarily Briggs & Stratton lawn mowers and some MTD models. It traps dirt and debris before they enter the carburetor, protecting engine performance and longevity.

Fitment & Compatibility

• Direct OEM replacements: Briggs & Stratton part numbers 698369, 4216, 5088, 5099, and MTD 490-200-0011.
• Common applications: Most Briggs & Stratton single-cylinder engines found on push mowers, riding mowers, and generators (e.g., Series 450, 500, 550, 600, 625, 675, 700, 725, 750, 800, 850, 875, 900).
• Before buying: Remove your old filter and measure the outer diameter (roughly 2.5 inches) and thickness (about 0.75 inches). Compare to product photos—these are round, flat foam discs, not cylindrical or pleated filters. Check your engine model number (stamped on the valve cover or blower housing) against the OEM cross-reference list if you’re unsure.
• Aftermarket fit: These are not genuine Briggs & Stratton parts, but they match the dimensions and density of the originals. If exact OEM spec is critical, choose the brand-name version.

Key Things to Know

• Easy to install: No tools needed—just pop out the old foam, clean the housing, and press in the new one. Takes under two minutes.
• Washable but disposable: Foam can be washed in warm soapy water and re-oiled, but at this price, many users just replace both filters yearly. Do not run dry; lightly coat with foam filter oil or engine oil (squeeze out excess) before installing.
• Check for oil saturation: A dry foam filter lets fine dust pass through. Oiling is essential for proper filtration, especially in dusty conditions.
• Common gotcha: These filters fit only foam-style housings—not the rectangular paper-element or pre-cleaner types. Verify your mower’s air cleaner cover is round and snaps over a foam disc.

Should You Buy It

If you own a Briggs & Stratton mower that uses a round foam air filter and want a cheap, effective replacement that works as well as the OEM part, this two-pack is a solid buy. It’s ideal for routine maintenance—swap both filters at the start of the season and keep a spare. Skip it if you need a paper filter or a specific high-density foam for heavy-duty commercial use.
