Glow Plug Removal Set

This kit was almost completely useless for removing the broken glow plug from my Mercedes OM648 engine. The only marginally useful items in the kit were the long T-handle tap wrench and the M10x1 tap, which did serve to chase the threads clean after I finally got the plug out by other means. It does look to be nicely made, but it's applicability to my engine looks to be severely limited.
