NGK Diesel Glow Plug P/N:5909
NGK 92340 diesel glow plug for the 2014-2017 Mercedes-Benz Sprinter 2500 4-cylinder 2.1L and other vehicles heats the combustion chamber so a cold diesel engine can start. It is an OE or equivalent design for diesel engines that use ceramic glow plugs from the factory.
A glow plug that is wearing out can show up as hard cold starts, white smoke at start-up or a glow plug warning light. Those signs alone do not prove the glow plug is at fault; a weak battery can make a cold engine slow to start too. Each cylinder takes one plug, so a 4-cylinder 2.1L engine takes four.
This glow plug is listed for a wide range of Mercedes-Benz and Freightliner models, led by the 2014-2017 Mercedes-Benz Sprinter 3500 4-cylinder 2.1L and the 2016-2017 Mercedes-Benz GLE300d 4-cylinder 2.1L. If your vehicle is not named here, find it by year and engine on the Buyer's Guide tab.
