What It Is

This 2-pack air filter set (493910/691667) with pre-filters (272477S/272477) replaces the factory filtration on Briggs & Stratton 4166, 5075, 5075H, and 5075K engines. Designed for vertical shaft engines in Cub Cadet, Toro, and similar lawn tractors, it traps dirt and debris before it reaches the carburetor, extending engine life.

Fitment & Compatibility

• Engine models: Briggs & Stratton 4166, 5075, 5075H, 5075K (check your engine’s model number, not just tractor brand)
• Tractor models: Fits Cub Cadet 28A702, 28B702, 28B707 and Toro models with those engines
• Measurements: Main filter approx. 5.5" x 4" x 1.5"; pre-filter fits over it snugly
• OEM vs aftermarket: This is a direct aftermarket replacement for OEM Briggs & Stratton parts. Always verify your existing filter’s part number (493910 or 691667) before ordering
• What to check: Look at your engine’s model/type code (stamped on the blower housing). If you have a different engine series, this will not fit

Key Things to Know

• Quality: Users report these filters are dense and seal well, comparable to OEM. Some note the pre-filter foam is slightly thinner than original, but still effective.
• Installation: Easy – remove old filter, slide new one in, press pre-filter on top. No tools needed. Takes under 5 minutes.
• Gotcha: The pre-filter orientation matters – the open side should face down toward the carburetor intake to avoid bunching.
• Longevity: Replace main filter every 100 hours or annually; wash pre-filter in soapy water between changes (let dry fully before reinstalling).

Should You Buy It

If you own a Cub Cadet or Toro lawn tractor with a Briggs 4166/5075 series engine and need a budget-friendly, reliable air filter replacement, this 2-pack is a solid value. It’s ideal for routine maintenance – just confirm your engine model matches and you’re good to go.
