I can do that Richard!
At about the recommended mileage I removed the factory-fitted sparking plugs from my V6. They were the type with three earth electrodes and I was surprised to find them in perfect condition after no intervention for 67,500 miles.
I replaced them with NGK PFR6N-11 (platinum) also with triple electrodes, but it was obvious that the originals could have provided good service for a lot longer.
