The 41-810 also cross references with the TR6 and the TR4-2 though which means the heat range isn’t specified. The ACDelco 41-104 is mentioned in the Corvette forum as the same heat range as the TR6 but I have no proof, just one guys word.
Maybe this will help..? No GM part nos, but I think it’s a good cross reference for 1-2 step colder, etc, and gives some additional details re: compression, etc..
All that info but no ACDelco part numbers! Damn.
Sonofa!I didn’t get enough abuse so I thought I’d replace the fuel filter that Amazon delivered today. I usually YouTube this shit just to refresh my memory in case there’s anything I forgot but I figured, it’s just a fuel filter. Remove the fuel pump relay, start the truck and let it run until it dies. That removes all the pressure, right? Apparently not. I unscrewed one of the lines and it looked loose but wouldn’t come off the filter so I repositioned my head right under it with the work light shining on it so I could see real good and wiggled the line a bit and then it let loose. And the gas hit me right in my eyes. Luckily I was wearing my glasses but it still hit my eyes pretty good. Blinded and not wanting to open my eyes since I could feel it burning, I blindly climbed out from under the truck and wandered into the garage. I felt around until I found a roll of paper towels. Oh man that hurt. All I could do was laugh it off. Been a rough day. Fuel filter change complete.
Damn. A lot of work to find out the Beast wants you to change plugs every 5k miles eh..? Weak..!
It’s been 8k and the old plugs looked fine anyway. They aren’t the problem with my cold starts, I’m still working on that. Tomorrow I’ll see if it was the fuel filter but I doubt it. I’m just hoping it’s not the small intake manifold leak has got bigger, enough to cause it.
Amen brother. And I was just throwing a number out there on the plugs. How often do you actually need to change those copper ones?
IDK, I only put about 8k a year on it and I’ve put 2 sets on in the 2 years since I installed the blower but not because they needed to be replaced , more because I had problems burning plug wires and since I had it apart I replaced the plugs too since they were only about $20 a set. I haven’t ever just changed the plugs because they needed to be replaced.
Copper plugs should last 75k to 100k miles under most conditions
I didn’t pay attention when I pulled them out but I did check them out closely when I put them back in the second time and it wasn’t cracked and the electrodes looked fine. What is also funny is that with the ruthenium’s in both banks, #7 also recorded quite a few misfires but none with the TR6’s in the opposite bank. Both times the ruthenium’s were in all 8 cylinders, #8 misfired like crazy and #7 misfired quite a bit. It almost reminded me of when I put LED tail lights in and there was no problem but as soon as I put led’s in the front turn signals all of them combined caused my main brake lights to quit working until I added load resistors to the fronts. I know it sounds weird, but it’s almost like the system could handle 4 ruthenium’s but not 8....like there wasn’t enough of a load. I do have MSD Blaster coils too, not sure if that affected it. It’s like it was possessed lmao.
I highly doubt the same plug went back in that cylinder but who knows, I was out of patience by then and my hands were bleeding.

Edit: hey I have an idea- I’ll send you a set of free ruthenium plugs with less than 100 miles on them and you can install them and see if one is defective!
