A metallic plug operates at a different temperature limit than a ceramic one, so the answer to all of your three statements of quick/smooth starting, damage, and compatibility all revolve around if they're operating at the proper temperature and the capability of the "existing" ECU calibration to operate them at such.

What most owners don't realize is that if these metallic plugs operate too hot with the existing cal, then you'll suffer issues 2 and 3 in your list. If the glow plugs are too cold, you'll face issue 1 and 3 in your list.

I will wait to reserve judgement on the statement about "tests according to engine OEM testing protocols" until I see a picture of a glow plug instrumented with a thermocouple and the validation of the temperature at all ambient conditions, and ran some many hrs of durability test in an engine.

Look at it this way, Etecno1 have been designing and manufacturing glow plugs for 30 years. Given the choice between them and Chrysler to provide the best solution for our engine I know where my money will go.

This is not a case of getting a free set of plugs. I have had no problems with the original equipment ones and could just sit and watch.
I am happy to install and test them in this environment, once I know they are not going to strip the treads or hit the cylinders - which now seems to be confirmed.

You missed my point. Etecno were looking for serious volunteers to test these plugs and were overwhelmed with offers. Part of being a tester is, indeed, taking the risk that they will strip, hit the cylinders or even fall apart in your engine. A set of calipers and thread gauges, however, will tell you that the first two will not happen. If you're not prepared to take this risk you should have let one of the other many volunteers have this opportunity.

I'm sure that there are owners out there that do currently have problems with the OE plugs, can't get replacement ceramic, don't wish to go down the Chrysler "bodge-n-patch" route and would have been more than willing to install these plugs immediately.

If everybody approached it with this skepticism then the plugs would never get tested and, let's face it, the sooner they get validated the better for all of us.

...If anything, a metal surface (a heat conductor) would transfer the heat better than a ceramic surface (a heat insulator). In theory, a metal tipped plug would send more heat into the combustion chamber and less into the cylinder head casting where the glow plugs screw into the head (might be why some of the ceramic glow plugs get stuck).

Interesting. Probably true.
Though, if Etecno1 makes their steel glow plugs like others, the heating coil(s) will be packed with ceramic powder and encased in a metal sleeve. Maybe the reason Bosch went with a ceramic tip (ie didn't include the sleeve) was to keep the heat from transferring (being reflected) back up the plug.
_______

Aside from this, from what I have read, ceramic plugs heat faster but seem to be very similar in temperature to steel. I currently have 3 ceramic and 1 steel plug in my truck. The steel plug is 11.5 volts (kind of like putting a 60W bulb where a 100W should be). Without the plug the truck starts poorly. I scraped frost off of the windows this morning and started the truck with no problems.

We own diesel unlike our neighbors, we are adventurous, why are we hesitant to try a new plug?

-2*C (30*F) and strated no problems this morning. Still not cold enough for real testing. January will be the real test when temperatures here get down as low as -30*C (-20*F)

I agree with squeeto... why is everyone so paranoid to try a new plug? It just a Glow Plug and many other diesels are running steel plugs. Worst case it will start rough if they do not work properly.

Thanks Racertracer for parting with an oem Plug to resolve my dilemma. I owe ya one!! Now time to get dirty and turn some wrenches.....

Well, all went well with the used Glow plug for about 3 days. Then CEL and OBD said it was #3 glow plug again, But reversed harness makes the #2 glow plug the bad one. Thank you multimeter, the #3 would of been a bear to get to. Well back to plan B and find another used GP or wait for the new plugs to be released. At this point I might as well wait and hold my breath......................

Any update upon when these will become available? Just blew the glow plug code and I guess I am in the holding pattern to get a set of these.

I have good used ceramic one available.

Just received an update from Cristiano @ etecno on the Gx3123 7 Volt Glow plugs:
Hello Steven,
glow plugs will be available next week, they're leaving production line by Friday and we'll start shipping to dealers on Monday,
There's no need to pre-order since we've planned 400 pieces which i find enough for this first run. We'll entering production on a 30 days regular basis with this item, so they will be easy to find and affordable.
Best option is buying from www.dieselglowplug.com , those guys are directly connected with us and is the first company getting new glow plugs once available with a few hours delay.
Thank you for your interest, glow plugs are doing very well by the way.
Regards.
Cristiano Bondani

Ordered 4 and holding my breath till they arrive for an Installation Party..

I guess I'll be a tester for the guys still holding the test plugs!!!
