It's all bull, that burn stuff is all advertisement. Once fuel burns it burns, the only difference may be heat ranges yes however the OEM spark plug is made for the engine. Also make sure you torque the spark plug because you can have it to loose and then the spark plug might not make it all the way in or you can have it to tight and it reaches to far in. Also just smart anything engine or transmission related best to torque it. Other stuff is just as important but other things may not cost as much whatever.
Thing is just stick with the OEM or at least OEM Substitute plugs. I use Bosch Copper Plus and they work great, I did foul my Bosch Platniums but I need to do a valve job and just haven't found the time. But for now the coppers are doing great the engine sounds much better and especially after I cleaned my throttle body it idles so smooth.
As far as performance chips and stuff I don't believe in all that garbage sorry if this offends some people out there, but im just a old timer like truck guy. I like fuel injection and computers but those stupid expensive chips make no sense in a truck.
Anyways use what you want to use but personally you might not benefit to much from switching. Just be sure to gap them and check the gap even if pre gapped also make sure the reach is the same and to torque them also use anti-seize for the sake of it. 1.29 won't kill you
