NGK Glow Plug for Mercedes-Benz E250, GL350, GLK250, ML350, S350, and Sprinter 2012–2025

NGK glow plug 92340 serves the Mercedes-Benz diesel applications listed below, including the E250, GL350, GLK250, ML350 Bluetec 4Matic, S350, and selected Sprinter vans. NGK identifies this plug as CZ551. A glow plug supplies heat to the combustion chamber to help a diesel engine start when cold. It works with the engine's glow-control system, so the correct plug reference matters as much as the vehicle name. The listed passenger-car and SUV applications span selected years from 2012–2016, while Sprinter coverage includes selected 2020–2025 models. Check the individual year, model, and trim in the table before ordering; these ranges do not mean every Mercedes-Benz diesel uses the same plug.

Warranty: 24 Months / 24,000 Miles.
