Description
Overview:
This Air Filter Base is a Genuine Briggs & Stratton component designed for selected 104M-series engines, including 104M02-0083-F1 and 104M02-0021-F1. It is a moulded, durable plastic backplate that sits between the carburettor and the air filter element, providing a stable mounting point and a reliable seal for clean intake air. By keeping dust and debris out of the engine, it helps maintain performance, starting, and fuel efficiency while reducing wear. Built to the original specification under OEM part number 594574, it ensures a precise fit with the matching air filter and cover. Suitable for common small garden machines such as walk-behind lawn mowers and other equipment using these Briggs & Stratton engines.
