Parts Desk Insights
The L82YC is one of Champion's most widely used small engine plugs — it covers a broad range of 4-stroke applications from small outboard kickers to lawn equipment. If you're doing seasonal maintenance on a small 4-stroke engine, replacing the spark plug is one of the lowest-cost, highest-impact tune-up steps you can take. A fresh plug restores easy starting and smooth idle on engines that have been sitting.
For other Champion marine spark plug options, see the Champion L76V #827M or Champion L78V #833M for 2-stroke outboard applications. For a broader selection of ignition components, browse our Ignition Components collection.
