Description
Overview:
This round air filter is a non-genuine replacement for Briggs & Stratton part 390930, designed for use on Briggs & Stratton 170400 and 171400 series engines found on many garden and construction machines. It uses pleated cellulose paper media for fine dust capture, supported by a perforated steel core with moulded rubber end caps to seal securely in the airbox. The filter helps maintain clean airflow to the carburettor, protecting the cylinder and improving starting, performance, and engine life. Dimensions: outer diameter 108 mm (4.25 in), inner diameter 98 mm (3.86 in), height 51 mm (2.01 in). If your machine specifies B&S 390930 or matches these dimensions, this element offers a reliable, cost-effective service replacement.
