Anyone else notice spark plug quality/life going downhill?

SO I hang around with a pretty large group of car guys. all with various brand preferences of carbs, ignition, etc

some SBC, some mopar, some ford, some HEI, some MSD....you get the idea.

All of us recently have had issues with fouling spark plugs. Had a buddy literally have 8 junk plugs after a few months.

Just left a buddies house with a SBC in a truck that had ran great all summer. Started running rough after maybe 800 miles since a plug change. started running bad. sprayed some water on the headers, 3! Dead tubes! HEI big cap distributor. Tested spark out of the cap and fine...so dead plugs

delco's, champions, autolites…. I run NGK, and i'm sticking with them as I haven't killed one of them yet.

just wondering if anyone else is seeing this trend? or if its just my group of boneheads.lol
 
99 % of the time, fouling is the result of a too cold plug
 
Or bad AFRs
My Copper Champions have been in there since 1999 and have over 100,000 miles on them.Hyup 5 zeros. I bought a new set in 2004, thinking it might be about time. But after the car went 93 in the 1/8th on the 5 year/50,000 miles old plugs, I just put them in the trunk.
FWIW, I run the old Accel square-top big Yellow Super Coil; I think I could make a welder with that coil.My engine don need no steekeen' multi-strike CDI.

But yes, in the powersports world, we even noticed something going on in the NGK line. I won't say the quality went down exactly, but we definitely had more issues after about maybe 2008ish. Random quitters, just as you experienced. On a 1-cylinder that sucks, and the customers were quick to point that out.
