There is nothing wrong with platinum plugs in forced induction engines.
Many import turbo's come with platinum as the OEM plugs as well.
It's only nitrous that should not run platinum plugs.
Now
NO car should even run Bosch platinum.
ESPECIALLY a FI'd car. Bosch has basically given a black eye to the platinum plug crowd with their POS products. (melted tips, dropped electrodes, shattered porcelin
)
BTW - the stock plug in the new S/C modular engines is the 22FS
