Solid ,Removeable Nut, Threaded. I ordered a plug for my HF generator and got the wrong one. I got the threaded post but no nut. Couldn't find one anywhere in my shop.......There is a code for them but I cant find it now......I called them a year ago and they told me what it was, and sent me a few nuts.

NGK Iridium are only good for 50k. If replica plugs are good for 60k+, what's the point of buying "real" plugs?

Those fine wire electrodes have left the room.

I ran some NGK V-Power (copper) plugs in the Lumina for 42k miles. The "V" grooves were practically gone. It's a waste spark ignition so 42k might be more like (running issues.

Coppers need to go out at 30k. I run Delco's in my old Oldsmobile's 3.1l w waste gate and seem to run the best. Had tried V-powers and U-grooves but plain Delco's were the best.

No, they have (2) different variants. They have a long life version rated for 100k 105k miles.

Kinda doubt the fakes would go 30K letalone 65K. Sounds like you got your monies worth.

IMHO, never buy parts off of Ebay or Amazon, unless it's store front from a reputable parts supplier. For the last 30 years, I have always bought my plugs from the dealer. Can't be bothered dealing with ghost issues and drivability concerns because of crappy spark plugs. If not the dealer, I would use RA to find the OEM Equivalent (i.e. Denso) part.
