2009 Ram cc hemi , changed mine to Platnuims at 48,000 , changed again at 150,000
truck has 189,000, no PROBLEMS IN PLATNUIMS

 

What kind of platinum did you use? I wouldn't assume they all would work. I've seen Bosch platinums fall on their face in a dodge, and their +4's pull it off.

Here is the plugs for the 6.1 if some of you guys like them in your 5.7 hemi trucks.

I`ve run mine well past 60,000 miles on the original plugs, still looked VERY GOOD when i pulled them @ 60,000+ miles.
I dont see any reason for changing them at 30,000 miles... other than the dealer is makin a boat load of cash on parts and labor @ every 30,000.

 

I got a set of 16 earlier this summer for $60 shipped from RockAuto.com.

Post the exact link for the plugs you bought then.

 

There isn't really a 'page' for the specific part on RockAuto.com, you get a list of available options when you drill down into vehicle type and part type. Go to this page and look for NGK #92174. $3.52/ea. NGK stock number 92174 is the LZFR5C-11 part, as you can see

And you're welcome.

 

How hard are they to change? Not nary coil over mess is there?

 

It's not bad. Takes some time, just due to having 16 of them. Each has a coil pack, but they remove easily. A couple on each side are tight but as long as you have a few different socket extension lengths it works OK. Just putzy. Easier to get to them than they were on the same Hemi in my old Grand Cherokee.

Many thanks rob... posting the part numbers helps old geezers like me to find them easier.
