MadMax:
The oem plugs are rated at 100k. Is there a drivability, or other issue that causes you to think they are worn out? I like to run the oem spec plugs in my vehicles. Champion Coppers are good plugs, but not really beyond 50k. Dodge specs that they be changed around 30k. If you shop around, you may be able to get a little better than $17 per, but there are only 6 of them. $100 for plugs every 100k, isn't bad.
Remember, the Hemi has 16.

Double check it, but I find a set of six Mopar SP1492125AE plugs at this link for $79.

BTW, it appears that there is an AF version that has replaced this AE version.

When I remember, I always depress the Autostart disable button on my 3.6L Durango, so no AS for me.

I believe NGK makes them for Dodge. You can probably find the same plug sans the Dodge name for a bit less. They are darned good plugs though, so I'd stick with them if you can.
