Spark Plug Help

[captjanes]

i wants to change the plugs in my jeep and i like some opinions on what is a good brand to buy.. it says a on my hood that stock is RC12ECC. but i am not a big fan of champion plaugs. i run bosh platinums +4 now and the top broke off one plug and went down on my piston. so i am not using that brand anymore. is there any cross reference that i could use or can someone recomend me a good brand.. what about NGK Iridium?? thanks in advanced

If your going to spend 8.99$ per plug to buy NGK's take a good look at Diamond fire E3 plugs.

I personally love champions. They are the only plug that I run when I use nitrous. And not platinum. They just melt.

I would stick to NGK Champion or Autolites. I used Bosch and PT+...E3's The stock NGK worked the best and lasted the longest. The E3's gave me lower MPG and some misfiring issues.
