Those of you running the Bosch Platin plugs, how often do you replace? Do you replace them per OEM

For modded cars I'd replace them sooner than OEM recommendations.
Personally, I do it about every 20k miles (I think OEM spec is 40k miles).

I read, "Combat pre-ignition with this 1-range colder plug than the OEM PFR6Q plug"
as, "Combat pre-ignition with this 1-range colder plug, the OEM PFR6Q plug"
My mistake.
