Power Distributors 5043K Air Filter Cartridge Small Engine

Product Description

The POWER DISTRIBUTORS 5043K is a replacement air filter cartridge designed for small gasoline engines commonly found on walk-behind lawn mowers and similar outdoor power equipment. It protects the carburetor and internal engine components by trapping airborne debris before it enters the air intake. This cartridge is the DIY-market equivalent of Briggs service part 491588S and is compatible with the optional 5064K pre-cleaner for added filtration in dusty operating conditions. Licensed HVAC and outdoor power equipment technicians, as well as knowledgeable DIYers, will find this a direct-fit service part for routine seasonal maintenance.

This air filter cartridge fits Briggs and Stratton 3.5 HP to 5.75 HP Quantum engines and 3 HP to 5 HP horizontal shaft engines in the 625, 875, and 900 Series.

The cartridge can be used alongside the 5064K pre-cleaner when operating in high-dust environments to extend service intervals and protect engine performance.
