Turbo engines
If you seek to replicate the turbo engine variant you should be using the turbo variant plugs, not OE for a naturally aspirated truck engine.

platinum plugs stay too hot (that's why they run cleaner) and cause premature ignition in turbo and supercharged engines. the platinum burns off in turbo cars, they simply come apart under high cylinder pressures. Running them could cost you your engine.
