5 CYL 1990 to 1993 300D 2.5 Monark Glow Plug Set w/ Manual

Set of 5 High Quallity German made Monark Glow Plugs complete with a detailed manual written by Kent Bergsma. Many who own these cars complain they don't even know where the glow plugs are and are worried they could never replace them on their own. A shop will charge you a lot of money to do this job. It is time consuming but not rocket science. You have to remove the intake manifold on this engine to get the plugs replaced. My step by step illustrated manual with take you completely through the correct process. Glow plugs even come with locking nuts. These glow plugs also fit 1989 190D 2.5 (only 1989!)

To complete successfully you will need a new intake manifold gasket. CLICK HERE to order.

I also recommend if you are going to the trouble to change the glow plugs be sure and ream out the carbon in the pre-chambers. Excess carbon is the number one reason for glow plug burn out. CLICK HERE to order my custom made all steel glow reamer.
