Keep your Briggs & Stratton engine breathing cleanly with this genuine panel air filter, SKU BRI491588S. Manufactured by Briggs & Stratton, it replaces OEM part numbers 399959, 491588 and 491588s, making it a reliable replacement for routine servicing. The panel measures 133 mm long, 114 mm wide and 19 mm high (5 1/4 in x 4 1/2 in x 3/4 in), a compact rectangular element that traps dust and debris before it reaches the carburettor.
