Description
Overview:
The Base-Air Cleaner for Briggs & Stratton engines is a genuine replacement part that forms the lower housing for the air filter assembly. Made from durable, moulded polymer in a robust, workshop-friendly finish, it supports and seals the air filter so only clean air reaches the carburettor and engine. This helps maintain performance and reduces internal wear in everyday garden and light construction machinery powered by Briggs & Stratton engines. It is designed for selected models including 16N132 and 19N132, among many others. As an OEM part (OEM No. 591804), it offers the correct fit and alignment of mounting points, ducts and seals, making servicing straightforward and helping to restore original intake efficiency.
