911 ... got fire?
most people say use stock plugs, or ngk tr6 if youre using boost or nitrous. i currently am running the bosch +4, and people often say bad stuff about them, but they seem pretty good to me.
^^^ Ditto. I have been running the Bosch +4 in my 98 2.4 for over 5 years with no problems. Car runs great!
98 Z24

RIP Specks
I use NGK iridiums and they run great the only plugs people complain about are the Bosch +4s though like they said some people dont have a problem. Also the Bosch o2 sensors can give problems too so I just avoid Bosch in general.
