Sorry to hear about Autolite woes. I personally have never had a problem with them but I have read that the Ford diesel crowd does not like them. I've had a set in my 86 Golf D for seven years and I'm sure they could be replaced but they still seem to work properly. Back when I bought them the price differential between Bosch was at least 33% so I opted for the Autolite.

The NGK I've also had, in a 1982 Datsun Maxima diesel and I found them to be a very good plug. The key I think with any glow plug is to always run the same manufacturers plugs and do not intermix brands. The specifications for each maker are slightly different and mixing can be a problem.

Fortunately I have a pretty healthy supply of Monark diesel GP's for the VW idi diesels and I have as well an extra set of Bosch for the TDI.
