Set of 5 High Quality Bosch Glow Plugs complete with a detailed Glow plug removal and replacement manual written by Kent Bergsma. These fit 124 chassis 300D 2.5 from 1990 to 1993, and 1989 190D 2.5 ONLY. 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 new locking nuts.
Product Details
To complete successfully you will need a new intake manifold gasket. Look below 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. Look below to order my custom made all steel glow reamer.
BONUS: We also include a small container of nickle nti-seize compound which can prevent frustrating and damaging thread seizure. Only a small amount needs to be smeared on the center of the threads just before installing the glow plugs in the head.
