Out of my Liberty. Think they have about 40-50k on them, sitting at 200k now. Came out super easy. NGK V power nickel (put the same in). Old ones came out with a .050" gap, new is .040".

They look nice, but would need closeups of each gap and insulator nose to really tell anything.
.010" gap erosion is sufficient to trigger a change, though. And having nice, sharp corners on the electrodes supposedly helps idle stability.
Which reminds me; my Camaro is due.

I don't like extended tip - but not as crazy as some fords

If theses are heat range 6, I might try a 7. I found the V power to run about 1/2 > 1 H.R. above factory plugs on anything I've run them in.

Any pinging or loss of full throttle power when working hard?

No signs of fouling as far as I can tell. Looks like they wore well and did their job.

Again, any pinging? Look a tad too hot. like I stated before.

I'd try a standard DENSO variant. Solved many Subaru running issues where the NGK factory p/n just didn't work well.
