Description

The NGK LFR6A is a spark plug designed for specific Yamaha marine and other engine applications. It features a V-cut in the center electrode to improve ignitability and a trivalent metal plating for corrosion resistance. The plug has a 14mm thread diameter, 1.25mm thread pitch, and a 26.5mm reach.

This spark plug is also noted to be superseded by the LFR-6A110-00-00. Before purchasing, it is crucial to confirm your Yamaha model, year, engine family, and the exact plug part number required by your service manual.
