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.
