I was afraid they were not going to come out at all.

I replace the Autolites with Monarks as I had already bought them. Monarks are not good either. One of the Monarks failed a year later.

I replaced them with Bosch over 3 years ago and have had no Glow Plug Failures since then.

There are local places that sell Bosch Glow Plugs but they are like $15-$16 each.

Somewhere in the Forum there is pics of Autolite Glow Plugs where it looks like the tip actually exploded.
