not sure what part# the autolites were they went right in the trash
What was the Part# of the autolites?
The next question is what GP to use. Here is where the fun begins. I profess using AC12Gs or Autolite 1109s. They are temperature limiting via. A built in positive temperature coefficient resistance coil in series with the heating coil. This allows the GP to heat to red hot and stay there without melting down. The normal failure mode of a GP is overheating. Caused by a controller going bad or a finger getting too heavy. At any rate a pain in the butt. Now if you want the ultimate GP, a BERU 007 is temperature controlled and a BERU that everyone holds in reverence.$21.15 at
For BERUs: https://www.real4wd.com/B1WebTools/c...spx?PartNo=007 $21.15
Check out this website: Glow Plug - Military Humvee 6.5L I've emailed them regarding their GP_65MILHUM GPs. They even have the correct terminal! $68.50/set + S&H.
Check them out if you don’t believe me. Whatever you choose, preheat them before you install them. Hook them up to 12V and watch them heat, you may want to do it in two stages, 1st heat them until they smoke. Let them cool as you test the others, then take them to red hot. If you have an ammeter to measure the current and they are temperature limiting, they should start out at around 10 amps and taper off to about 4 amps. If they continue to draw 10amps, they are not TL GPs.
Ya, those will work for 7.3L, Bullet connectors., But I need spades.
I guess I'm trying to understand what is to be gained by using these autolites? Maybe a few bucks...we all know the Beru's work and are good plugs. So I'm thinking why re-invent the wheel here especially when the consequences could be so great....head removal etc etc. I think I'll just stay with the Beru's cuz even at stealership prices it still far cheaper than the hassle of having a plug swell up and drop bits on my pistons. Just my .02 though.
Accuratediesel is claiming that their 6.9L GP's are self-limiting, and only 68.50 a set.
They also have GP controllers for the 6.9 for $65. Thats cheaper than I have seen them any where else.....
Well, as I said I would, I would post back on how the Bosch plugs performed.
AND, as you all said, the Bosch plugs lasted about 2 and a half months and then one by one, they started burning out...
I am running a controller setup...but the controller fires by a push button due to the wiring hack job.
The reason why the truck burnt out plugs before was because it had the SAME plugs in it then as I do now....but that is going to change!
