Is there a need to change OEM plugs for cooler ones when flashing the ECU?

Which plugs are recommended?

Some tuners stick with OEM, some tuners recommend others, I would check with your tune provider.

I run the PK20PR-P8 with absolutely no issues. Not one misfire ever.

We are running the Bosch Motorsport F5DPOR plugs on our shop car with 3076 turbos. They're gapped perfectly out of the box for all the cylinder pressure a stock motor can take at 0.025", 1 step colder than OEM. Highly recommended.

@A418t81's Denso PK20PR-P8 plugs have also done exceptionally well on his car with OEM VTGs setting a number of record runs and no issues reported.
