The only confusion I can see may be between the M103 and M104 engines. What's yours?

M103, multiple guru posts recommend it, as long as its copper core and non resistor it should be good for my car, I replaced them 9 years ago, just pulled one out, its pretty darn clean for the age, around 18K miles on them, Champion RC12YC copper core non resistor.
The Bosch F8DC4 sound be fine, same spec as Champion.

The correct copper core non-resistor plugs are going to be Denso T20EPU or NGK BP5's, both gasketless. The M103 head has a beveled seat for the plugs. The Bosch plugs are flat seated. If you decide to use them, cut the gasket off.

Thanks Jayare will do.

You'll most likely need to get these from an online seller. Also try ClubPlug.net

AutohausAZ does not carry the correct plugs for the M103. They have not in the last 4 years.
I would go with other online sellers.
