Question Glow plug opinions

Since this is glow plug season lets have opinions on glow plugs! From reading here it seems the general opinion of Monark and Champion plugs is not very good. How about the difference in cost between Bosch & Beru is it worth it? Anybody have experience with NKG or AC glow plugs? Any other brands out there? Don

Just replaced mine today with Berus. I've had the car 12+ years, and had never replaced them. Two weeks ago the plug lamp stopped lighting, and two days ago I almost got stuck almost 100 miles from home because it was resisting starting. New plugs went in easily, with no issues. Berus were only about $2 more each than Bosch's from Phil at Fastlane...

No NGK for MB. I changed 2 sets in a year... I cost a lot.
Just got a reply from them saying that if they burn its because of to high voltage or current applied too long. DUH! I have the after glow on my mercedes and I think a lot of MB models have it too.
Therefore, NGK, before saying that this glow is compatable you should check what your glows are able to. They just burn in the E300TD, BERU, still strong.
What to use? I'll go for Beru as MB use, perhaps the new Bosh chromium, garanty 3 years, cannot get wrong with such a statment?

Autolites are the worst.

Bosch Glow Plugs are almost as good as the Berus and cost less.

Besure, to ream or otherwise clean out the built up Carbon from the Glow Plug Holes. As it can shorten the life of the new plugs.
Also nice to put some Never Seeze type compound ont the Glow Plug Threads.

Good advice on the thread, I always put some anti Seeze, its important as they don't get stuck.
The build in carbon would burn with the heat created by the glow?
The build in carbon related to my letter is because they were "DEAD" or "BURNED". Of course the carbon will build up, there is nothing to burn it as the glow is not working.
also after those NGK, when I put the new BERU in, it was tighter abd I had to push them in, this with the carbon build up, then there is a problem with the NGK been slightly too thin compare to the BERU, making them building up carbon in the HOLE.
Again, NGK is a No NO go

Mine came new with BERU's. I'm still using the original ones. If I ever have to replace them, I'd pay double or triple the price to get the same kind of service life.

Beru are as expensive as NGK, but the latest will not last... This put in perspective the "expensive"...
