This Pre Cleaner Filter is a genuine Briggs & Stratton component designed for the 31 HP (approx. 23.1 kW) Series engines. Made from durable open-cell foam, it sits over the primary air filter to trap coarse dust and debris before they reach the main element, helping to maintain clean airflow and stable engine performance. The foam construction provides reliable filtration in dusty working conditions common to garden machinery and site equipment. As an OEM part (No. 692520), it offers the correct fit and function expected for Briggs & Stratton engines, helping to extend the life of the main air filter and reduce maintenance interruptions. Suitable for equipment powered by the Briggs & Stratton 31 HP Series found on ride-on mowers, lawn tractors, and industrial applications.
