Cleaning out your glow plug holes from excess carbon (coke) can increase fuel economy and will extend the life of your glow plugs. This important regular maintenance procedure is commonly neglected and will lead to rough starts, smoke at startup, decreased fuel economy, and engine shake.
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.
For a limited time purchase this set of FOUR glow plugs for $47.95 and receive the Mercedessource custom built steel housing glow plug reamer for $26 (regular price $39.95). Comes with complete instructions for replacing glow plugs and reaming glow plug chambers. Excess carbon build up in the prechamber is the no. 1 reason for premature glow plug failure. We recommend you always ream the holes with changing pencil glow plugs.
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.
Limited time offer. This is one deal you can not pass up!
