This 4 way glowplug wrench is a handy tool for removal and replacement of glowplugs on engine powered radio controlled cars.
The spanner has 7mm 8mm 10mm 17mm sockets and a storage place for extra plugs.
Since this version has the 17mm socket it can be used for the fitting and removal of wheels on the 1/8TH scale model cars and so makes the tool even more useful.
