my 300e-2.8 has no manuals and i'm relying on my usual resources to find an appropriate set. which bosch copper plugs are they anyway? i've tried searching the forums and the bosch site recommends platinums which everyone warns me away from. alternatively, i may want to use the ngk with the "v" electrode which supposedly gives you a better spark. those are easy to get. also, around here i couldn't find a place that stocked the copper boschs or find a cross reference - not pep boys or napa (will try strauss). also what i've found on the forums is that you can gap to .040 safely to get smoother running engine - does that sound right? thanks much for all the help thus far...
