795066 Air Filter Replace for BS 5419,796254 OEM Air Cleaner Cartridge with 796254 Pre Filter Fits Lawn Mower Air Cleaner Element

What It Is

This is a replacement air filter kit for Briggs & Stratton small engines, combining the 795066 air cleaner cartridge and a 796254 pre-filter. It’s designed for lawn mowers, tractors, and other outdoor power equipment using compatible BS engines.

Fitment & Compatibility

• Check your engine model: Fits Briggs & Stratton engines using part numbers 795066 (main filter) and 796254 (pre-filter). Common on Series 5419, 5451, 5500, 5520, 5530, and 5580 engines.
• OEM vs aftermarket: This is a direct aftermarket replacement for OEM Briggs & Stratton parts. Verify your existing filter’s part number matches either 795066 or 796254.
• Measure before buying: Main filter dimensions are approximately 4.5" x 3.5" x 2". Pre-filter is foam, about 4" x 2.5". Measure your current filter housing to confirm fit.
• Brand/Model check: Not universal—fits specific BS engines, not all mower brands. Cross-reference with your mower’s engine model tag (usually near the spark plug or valve cover).

Key Things to Know

• Quality: High user rating (4.7/5) suggests reliable filtration and good seal. Foam pre-filter traps larger debris; paper cartridge handles fine dust.
• Installation: Simple swap—remove old filter, clean housing, insert new cartridge and pre-filter. No tools needed. Takes under 5 minutes.
• Common gotcha: Some users report pre-filter being slightly smaller than OEM—ensure it fits snugly without gaps. If loose, dust can bypass.
• Maintenance tip: Replace annually or every 25 hours of use—sooner if mowing in dusty conditions. Never run engine without both filters installed.

Should You Buy It

If you own a compatible Briggs & Stratton engine and need a budget-friendly, well-rated replacement for the 795066/796254 combo, this is a solid choice. It’s easy to install and offers good value for routine maintenance. Not for non-BS engines or models with different filter housings.
