Description
Overview:
The Replacement Foam Pre-Filter for the LA1533 Briggs & Stratton air filter is a durable, open-cell foam sleeve that captures larger dust and grass particles before they reach the main filter. By acting as a first line of defence, it helps maintain clean airflow, supports steady engine performance, and reduces wear on the primary element. Designed for Briggs & Stratton engines rated at 12.5-17 HP (approx. 9.3-12.7 kW), it's well suited to garden and construction equipment such as lawn tractors and outdoor power units using the LA1533 assembly. The ring-shaped foam form is easy to handle and replace during routine servicing. Dimensions: height 77 mm; outer diameters 182 mm and 71 mm; inner diameters 155 mm and 44 mm. MPN reference: A2145/F.
