Seems like a good deal but are they any good? If not is their a site with a better deal on Bosch? Thanks

5 Cylinder 617 Monark Pencil Glow Plugs with Carbon Reamer - Package Deal!

For 300D 300CD 300TD 300SD w/ Instructions

Item: ELT-COM5MGWR $89.95



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.

 

I will check it out. I would still like to ream out the holes, would local part stores have this as well? Can I use any old cylindrical wire brush?

Thanks again!
