NGK Glow Plug for Mercedes-Benz E-Class, GL, GLE, GLK, ML, and R-Class Diesel (2007–2016)

This NGK glow plug heats the combustion chamber of Mercedes-Benz BlueTEC and CDI diesel engines so they start cleanly and run smoothly when cold. A failed glow plug causes hard cold starts, rough running, white smoke, and a glow plug warning. It fits diesel E-Class, GL, GLE, GLK, ML, and R-Class models from 2007–2016.
