According to Sparkplugs.com NGK does not make a copper plug for the 330i. Denso does model number K20HR-u11.

I agree these are easy to change but since the car was designed for iridium, not sure that copper is the best way to go but according to the sparkplugs.com site the above listed model will work. If you decide to go this route let us know how it works out.
