Overview

The Laranvi 491588S air filter kit brings together a complete filtration solution for small engines found in many walk-behind and rider mowers. This kit includes an air filter, a washable pre-filter, a spark plug (BR6S), and a fuel filter, all designed to help your lawn mower breathe easier and run more smoothly across the season.

What’s Included

• 1 x air filter
• 1 x pre-filter
• 1 x spark plug (BR6S)
• 1 x fuel filter

This combination is sized for a precise fit and comes in a compact, easy-to-handle package for quick maintenance tasks.

Design and Durability

• Premium filtration media paired with a sturdy metal mesh helps resist wear in dusty yard conditions.
• A soft gasket provides a tight seal, supporting robust engine breathing and reducing potential air leaks.
• The pre-filter is washable, enabling repeated use and enhanced long-term filtration.

In real-world use, these features translate to less filter clogging from grass and dust, smoother engine response, and a clearer path for air and fuel to mix for combustion.

Performance and Compatibility

• Designed to work with Briggs & Stratton engines and commonly replaced part numbers (491588S, 491588, 399959, and more).
• Also compatible with a range of Toro, Craftsman, and Troy-Bilt models, including popular walk-behind and small riding mowers.
• The kit’s exact sizing (5-1/4" length x 4-1/2" width x 13/16" height) ensures a close fit when compared to the original part.

Note: Always compare the shape and measurements of your existing filter to confirm a precise match before purchasing. This helps ensure you receive the right parts the first time, minimizing downtime.
