Late 240D Bosch Pencil Glow Plugs with Carbon Reamer

Application: Applies to the model listed above. Excellent quality. They are Bosch Duraterm brand glow plugs. 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. Kit Includes 4 pencil glow plugs and Glow plug reamer with 14mm tool with complete instructions for replacing glow plugs and reaming glow plug chambers. Excess carbon buildup 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.

The special tool included allows you to push in HARD on the reamer while getting it started in the glow plug hole. The 14mm box wrench has a tab welded on one side so the reamer can not pass through the box end.
