I have been running FR4 plugs with the Edelbrocks heads. The Edelbrock recommended plug is a Champion RC12YC. I have never had a Champion plug I liked and I saw many of them being returned due to failure in vehicles. Two plugs were recommended here. One is the NGK FR4, the other BKR6E. Remember, this is a factory dual quad car that is street driven with the occasional "blast". There is some soot on the body, which I am a bit rich but much I see a lot of gray on the electrode and ground. I had a set of BKR6E in my cabinet. Any reason not to run them?
Is there another recommendation? I might add that I am also running the Pertronix II and matching coil. Direct 12V power source to the module as instructed. The compression ratio is about 9.8:1.
Any suggestions would be welcome.
