Late 240D Monark 4 Pencil Glow Plug Set w/ Instructions

Application: Fits all 4 cylinder 240D diesel engines from 1980 to 1983 with pencil glow plugs. We have been so impressed with Monark Products that we have recently begun using their glow plugs. They are actually one of the last quality glow plugs still made in Germany. Even Bosch now makes their glow plugs in France, Turkey and other locations in Europe. Now don't get me wrong - Bosch is still a good product. But these Monark glow plugs are superb. They are built with the same materials and have the same specifications as the Duraterm pencil plugs. Even comes with 4 high quality locking nuts for the wires.

SVO WVO: If you are running SVO WVO fuel we have found that glow plugs may not last as long compared to running diesel fuel. The tips and chambers tend to coke up faster. Super important that you ream your glow plug chambers more often. These Monark plugs concentrate the heat more toward the tip and which keeps the glow plug ends cleaner.
