One New Aftermarket Replacement Air Cleaner Base Fits Briggs & Fits Stratton XR2100 Series Engines
This aftermarket replacement air cleaner base mounts to the carburetor on Fits Briggs & Fits Stratton (B&S) small engines, providing a secure seating surface for the air filter element and housing assembly. The base seals the air intake path to prevent unfiltered air, dirt, and debris from entering the engine, protecting internal components and maintaining consistent combustion performance. It is a direct replacement for the OEM part in the XR2100 Professional Series engine lineup, commonly found in walk-behind lawn mowers, generators, pressure washers, wood chippers, and mini excavators.
