The air filter cartridge cleans the air as it comes into the engine. It will remove any particles and debris, keeping the engine free from buildup and problems. The air filter will become dirty and clogged with regular use and needs to be replaced as a part of routine maintenance. This is typically done once or twice a season, depending on frequency of use. It may be necessary to replace intermittently if there is an emergency issue. Air filters cannot be cleaned and should always be replaced with a genuine OEM replacement. This OEM air filter can be used with Briggs & Stratton engines in select lawn mowers and blowers from Toro, Husqvarna, and Briggs & Stratton. This pleated paper filter includes a plastic frame. The foam pre-filter cleaner is sold separately, and this cartridge is sold as an individual unit. Air filter replacements require no tools, but it is important to allow the engine to cool completely and wear gloves when performing maintenance and repairs.

Pre-cleaner filter wraps around your engine's air filter to trap large debris before it reaches the main filter. Replace when torn or clogged to maintain airflow and engine protection. Verify fit by model number.
