50 Pack Rotary Air Filters - Fits Briggs & Stratton 491588, 399959, 491588s - 5.2x4.4x0.5 Inch

Got a bunch of small engines that use those rotary-style air filters?

This 50-pack is a great deal.

They're designed to fit Briggs & Stratton models that take part numbers 491588, 399959, or 491588s.

The size is roughly 5.2 by 4.4 by 0.5 inches, so they're the common flat-ish round style.

They're brand new, unbranded, but they're the right dimensions and they'll keep the dirt out.

Fifty filters in the pack—that's a lot of oil changes.

Keep 'em on the shelf for your mowers, generators, or whatever else needs a fresh filter.
