I had an 04 Dakota with a 3.7, now a 05 Ram with a 3.7, I have found that these engines eat sparkplugs up, What do you guys use, 4.7 guys we use the same plugs so feel free to comment

 

I used ngk iridiums when I replaced mine, hoping I won't have to replace them as often as the copper ones. I plan on pulling a couple to check the gap and condition when I get closer to 30k miles on them.

 

I just used the factory style champions. If your motor "eats" spark plugs that bad, I wouldn't go spending tons of money on expensive plugs.

 

my truck sits at about 2000 rpm for the cammute to and from work, the dakota i used bosch double platinums and they went 70,000 before trading the truck in. I had a host of problems with the Dakota when I first bought it, A misfire code was one of the last issues with it, changed them and didnt have any other problems. But after I wont use NGK again. I'll try the Champions because thats a name I know

Just changed the plugs on my 2006 Dakota 3.7 V6 today. 33,500 miles on engine. The dealor said it came stock with Copper Champions. Mine had NGK-R. Definitely needed to be changed. Looks like my Dakota chews up plugs as well. I replaced them Champion Double Platnium. My Truck runs better than ever. A little more pickup off the line. I am very Happy! Don't think the NGK-R was a good choice for this truck!

 

I wonder why its going through sparkplugs like that? I haven't had any problems with mine. I want to see some pics of your truck when you get the chance

 

Ngk-r is essentially an oem replacement, I think some years of the 3.7 had ngk's and others had champions but both were copper. From what I've seen on the standard copper plugs the gap opens up big time in just 20k miles, so at 30k they will be even worse.
