There are two factors that can influence your decision: preference and budget. Most plugs on the market will perform satisfactary as long as the match the manufacturer's guidelines and are gapped correctly.

I want to switch from champion rj12yc to E3 diamond fire spark plugs.witch E3 spark plug number?


The crossreference charts say to use an E352 to replace your Champion spark plug.

But, I can't understand why you would want to use this plug. I use only Autolite spark plugs, the cheap ones. All the fancy high priced spark plugs are not going to increase you horsepower or fuel mileage unless your engine is running badly to begin with. If you're fouling plugs, you certainly don't want to start fouling these expensive spark plugs. You need to fix the problem. But, here's the information you asked for.

Good Luck

Checked my spark plug today and found the tip to have browned of is this a problem with the mixture and how do I fix it?


I never heard of a brown plug. It should be black, blue, crud, or oil. The mix will turn the plug blue from being too rich, burning hot, and of course the black from soot or carbon, from being lean, Then the oil you don't want to see, but changing plugs is a must. I get great performance from Autolite plugs in my bike. 10 times better than champions. Clean the air filter while you are at it. Hope this helps.

I never heard that one, you should be able to see inside the tank and see if it is rusting or all gunked up. Pull the lines off and see if they run free and clean, change the filter, I would check the rubber lines to the fuel pump, they may be leaking air, vacuum assisted. Check the spark plugs. I had trouble with the champions, so I went and got Autolite 4163 plugs, they worked ten times better. 2002 S4 1999 750
