Planning on tackling this on Saturday. Going with the mopar copper plugs since they are a lot cheaper than the NGK IR plugs and I doubt I'll have the jeep for another 30k miles. I guess my main questions after reading this thread are:
1. I don't need to use antisieze since the copper plugs are pulled every 30k miles, correct?
2. The correct torque specs are 18-21ft/lbs for the copper plugs, not the initially stated 13ft/lbs?
3. The plugs listed on justfor jeeps says they are nickel plugs, I thought oem was copper?
The part number is different too. OEM is SPLZFRC11 versus SPLZFR5C11 on justforjeeps.
