Sierra 18-5199 Condenser - OMC 580321 Replacement for Johnson/Evinrude Outboard Engines

The Sierra 18-5199 Condenser is a direct-fit ignition condenser designed for use with select Johnson/Evinrude outboard engines. Each package includes one condenser, sized to restore proper ignition point function during a tune-up or point-set replacement. The condenser is manufactured to meet or exceed the specifications of the original equipment part it replaces, giving boat owners a reliable option for keeping their outboard's ignition system firing consistently.

This is a fit-specific part, so it is important to confirm the part number against your engine's original component before ordering. The 18-5199 is cross-referenced to the OMC 580321 condenser as well as GLM 70570, making it a straightforward swap for owners replacing a worn or failing OEM condenser on their Johnson/Evinrude outboard. It ships as a single-count item, ready to install as part of a routine ignition tune-up.
