Improve mower air intake performance with a practical foam replacement

The ZLKSKER 797301 Air Filter Foam Replacement is built to fit a wide range of Briggs & Stratton engines and compatible Craftsman models. Each filter piece measures 4.5 x 2.36 x 1.0 inches (11.5 x 6.0 x 2.5 cm), and the package includes two foams, giving you ready options for maintenance or seasonal stock.

Premium sponge for steady airflow

The foam uses a premium sponge designed for good air permeability, helping air move smoothly into the engine while catching dust and debris before they reach sensitive components. This balance can support reliable operation under different mowing conditions, without promising results.

Two pieces per pack, simple install

  • Two replacement foams are included, providing immediate spares for future maintenance.
  • Plug-and-play design ensures a snug, easy fit in compatible air intake housings, simplifying routine upkeep.

Wide compatibility

Designed to work with Briggs & Stratton engines (including 4249, 5433, 5433K) and a broad list of Craftsman models (as listed in compatibility notes). For best results, compare your air filter housing size and seal to ensure a proper fit.

Real-world use cases

  • Seasonal maintenance between mowing sessions to help maintain steady engine performance.
  • Work in dusty yards or windy days where intake air quality is challenged.
  • Keep a spare on hand for quick swaps during busy mowing seasons.

Quality you can feel

The foam is durable yet flexible, designed to hold its shape after installation and to tolerate routine exposure to air and moisture during typical lawn care tasks.

Care note

Foam air filters are typically replaced rather than cleaned in most setups. Follow your mower manufacturer’s guidance for replacement to maintain airflow and engine protection.
