It's still worth changing them earlier. These 3.8's aren't that fantastic. Those cylinders need all the help they can get and there is a noticeable improvement in how it drives after changing them. Given that these engines are prone to oil getting into the combustion chamber, a good plug makes a difference. Another 30k on those plugs would not be wise imo.

You didn't sound argumentative at all my friend.
How's your Jeep? Where are you these days? Somewhere exciting I bet! |

Those are for iridium. While I do run iridium's in my Honda, I've seen posts to stick with the OEM plugs, which are not iridium. Any opinions on which way to go?
I went to the 2012 JK Owner's manual and got the number I posted, which is RER8ZWYCB4. Why would that not be the number for the '12 OEM plugs? |

The question I answered was "What's the part number or the Champion number for the OEM plugs for a '12 JK?"

I actually just bought these plugs last week in preparation. They do show compatible for my 2013, and I do see places it says that is the OEM plug......but if I pull the parts diagram on Mopar's site it shows a part number of SP149125AE as the OE plug; however, those are iridium plugs as well -

SP149125AE and RER8ZWYCB4 represent the same iridium plug, which is listed as OEM plugs for the 2012 JK inquired about in a post above.

Just swapped mine out in Sunday. 2013 JK 3.6. What came out was iridium, so was what I put back.
Attachment 676228 I got the NGK plugs through Rock Auto. So far no complaints. My gas mileage seems to be picking back up to where it was a couple of months ago, and it doesn’t smell like it is running rich anymore. I changed mine out at 102,500ish miles, I’ve got about 100 miles on them now. The factory plugs where in way better shape than I expected. Attachment 676229 Too early to say anything except for initial impressions. They seem ok to me. The project wasn’t nearly as bad as I thought it would be, pulling the upper intake plenum (or whatever you call it) really wasn’t all that bad. I tossed in some new o-rings while I was at it. Attachment 676230 Happy Jeeping! |
