698369 Foam Air Filter For B-riggs & S-tratton Lawn Mower 698369 4216 5088 5099 MTD 490-200-0011 (698369 Air filter)

What It Is

This is a replacement foam air filter (OEM cross-reference 698369) for small engines on lawn mowers, tractors, and generators. It traps dirt and debris before they enter the carburetor, protecting engine life.

Fitment & Compatibility

• Check your engine model: Fits Briggs & Stratton engines using air filter part numbers 698369, 4216, 5088, or 5099. Also compatible with MTD 490-200-0011.
• Measure before buying: The foam element is roughly 3.5” x 2.5” x 1.5” (approximate). Verify dimensions against your old filter—some knockoffs vary slightly.
• Deck size is irrelevant: This filter fits the engine, not the mower deck. Ignore deck size specs; focus on engine brand and model number.
• OEM vs aftermarket: This is a non-OEM foam filter. It’s functionally identical but may feel slightly less dense than genuine Briggs parts. Works fine for standard residential use.

Key Things to Know

• Cleaning vs replacing: Foam filters can be washed in warm soapy water, rinsed, and re-oiled (use foam filter oil or light motor oil). Replace if torn or crushed.
• Installation: Push firmly onto the carburetor stud until seated. No tools required. Over-tightening the retaining nut can crack the carburetor base.
• Common gotcha: Some mowers use a paper filter with a foam pre-filter. This part is a standalone foam filter—not a pre-filter. Double-check your engine’s air filter housing design.
• Quality note: At $6.89, it’s a budget option. Expect shorter lifespan than OEM foam (replace every season or after 50 hours of use).

Should You Buy It

If you need a fast, low-cost replacement for a Briggs & Stratton or MTD small engine and don’t mind replacing it annually, this filter is a solid value. Avoid it if you require OEM durability for heavy commercial use—spring for the genuine Briggs part instead.
