Air Filter Cartridge Replacements for BRIGGS STRATTON 496077 691643 Generac 0691643 1691643 691643 John Deere AM34093 Fits for Briggs Stratton 176400 19B400 19E400 19F400 19G700

What It Is

This air filter cartridge replacement is designed for small engines in lawn mowers, generators, and other outdoor power equipment. It traps dirt and debris before they enter the engine, ensuring clean airflow for optimal combustion and engine life.

Fitment & Compatibility

Check your engine model number – not just the mower brand. This filter fits Briggs & Stratton engines with model numbers 176400, 19B400, 19E400, 19F400, and 19G700 series. It also replaces OEM part numbers 496077, 691643, 0691643, 1691643, and Generac 0691643. Compatible with John Deere AM34093.
Measure before buying: The filter dimensions are approximately 4.5" x 2.5" x 1.5" (L x W x H). Verify your engine’s air filter housing matches these measurements.
OEM vs aftermarket: This is a direct aftermarket replacement – not a genuine Briggs/Generac part. It should snap in without modifications, but check the foam seal alignment for a tight fit.

Key Things to Know

• Quality: User-rated 4.8/5 (118 reviews). The foam pre-filter and paper element are comparable to OEM performance. Expect 50–100 hours of use before replacement, depending on mowing conditions.
• Installation: Tool-free – simply remove the old filter, insert the new one, and secure the housing cover. No special skills needed.
• Common gotchas: If your engine has a separate foam pre-filter layer (common on 19G700 series), this cartridge may not include it. Confirm your housing design before ordering. Also, avoid over-oiling if you add a foam pre-filter – excess oil can clog the paper element.
• Price value: At $9.99, it’s 30–50% cheaper than most OEM equivalents, with consistent positive feedback on fit and durability.

Should You Buy It

If you own a Briggs & Stratton engine in the 176400/19B400/19E400/19F400/19G700 series and want a reliable, low-cost replacement that matches OEM dimensions, this filter is a solid buy. It’s ideal for routine maintenance on push mowers, generators, or zero-turn riders. Skip it only if your engine requires a specific foam pre-filter that isn’t included.
