It's not quite as critical for non-turbos as it is for turbos. The turbos develop high cylinder pressures that can disrupt spark propogation, so using the factory-recommended plugs is important. And Bosch recommends against using their 4-electrode plugs in the turbos - I've read that the electrodes have an irritating tendency to occasionally fall off.
My experience using Bosch plats and NGK BCP-7EVs in my Turbos is that the gas mileage was a little better with the platinums and the cars appeared to develop more power with the NGKs, as measured by the gluteal accelerometer.
I seem to remember that, for many years, SAAB also listed Champion plugs along with NGK plugs for the non-turbos.
