Thanks guys. I tend to be pretty impulsive and actually got iridium plugs the other day...but Champion not the NGK.
Probably won't get them installed until mid week.

I replaced my plugs a year or two ago....
I wanted to get the NGK Iridium IX plug like I use in every vehicle I have ever owned to find out that my 3.6 came with those plugs from the factory. So I basically did a plug swap with the factory plugs.....

*laffs* Yep.. discovered that myself.. like I said.. I'm impulsive. Ive got 72k on the car so I may just go ahead and swap them out anyway.

Can't hurt to change them out. I never like to exceed the manf. time recommendations.

Just be patient and careful, There's a lot of PLASTIC where you'll be working and it does break easier than "old school" metal parts !;)

I know there are a couple of threads on a couple different pages (with PIC's) on changing the plugs for the 3.6...do a site search for them if you need more help on the subject.:)

If you’re looking to DIY it, here’s a video I found. I’m about to hit 72k and I’m trying to decide if I wanna tackle it myself or have a shop do it. Best of luck! If anyone changes them themselves, let me know if there’s anything I should watch for! Thanks!

It is actually a pretty easy job for anyone who is mechanically inclined. Take your time and also have the intake gasket replacement set on hand. These are a recommended one time use item and are cheap at the dealer.

Any new suggestions for plugs on out 3.6l cars? Planning on a weekend roadtrip in mid September so I need to get the tune up parts on hand so we have them once the weather breaks and winter is pretty well gone. I have the RPM Intake Tube, need to get plugs, want to get the MSD Coils and P.U.G. lower intake so we can do that all at once.

Had them swapped for the proper plugs for my wife's 2010 Sebring not long after these posts.
Finally got the NGK Iridiums put [email protected] 92k for$140 labor I supplied plugs and gasket. Cheapest labor only quote I previously got was 175..highest 300.
The improvement in smoothness of acceleration performance and fuel economy were noticeable
