I guess if you want to try cheap chinese glowplugs these could be as good as any out there. The chance that they are Bosch is pretty much zero. There is a possibility that these will last ok but not much probability of that. I don't like changing glowplugs, too much of a pain to get them out. If they break or strip threads you won't like it much. Real Bosch or Beru yes, I won't even use Autolite too crappy for me. Just my humble experience, Cheers Dan
