What It Is

This is a two-piece air filter set (cartridge + pre-filter) designed for Briggs & Stratton V-twin engines found on riding mowers, zero-turns, and lawn tractors. It replaces OEM part numbers 692519 and 692520 to keep dust and debris out of the carburetor.

Fitment & Compatibility

Before buying, confirm your engine model number (stamped on the valve cover or blower housing). This fits Briggs V-twin engines in the 540000, 350000, and 380000 series, including models 541477, 542477, 543477, 356477, 358777, 380447, 380777, and 381447. It also replaces aftermarket cross-references 4232, 30-087, and 102-119. Measure your original filter: the cartridge is roughly 3.5” tall and 4.5” wide. Not for single-cylinder or small push-mower engines.

Key Things to Know

• Dual-layer protection – The foam pre-filter catches larger particles; the paper cartridge traps finer dust. Replace both together for best airflow.
• Easy DIY install – No tools needed. Remove the old filter cover, swap the cartridge and pre-filter, and reattach the cover. Takes under 5 minutes.
• Common gotcha – If your engine has a separate pre-filter housing (some models), ensure the pre-filter fits snugly. A loose fit lets unfiltered air bypass the filter.
• Check the foam – The pre-filter should be slightly oiled (use foam filter oil) for optimal dust capture. A dry foam pre-filter is less effective.

Should You Buy It

If you own a Briggs V-twin lawn tractor or zero-turn and need a quick, reliable air filter swap, this is a solid value at $12.39. It matches OEM specs and installs without hassle. Skip it only if you have a non-V-twin engine or need a different filter size.
