Platinum or Copper Spark Plugs
I have a 2003 1500 4x4 Quad Cab w/ the Hemi. I was at the local Dodge dealership having the computer reprogrammed for my over size tires, LT 285/70/17, and I was talking to them about the spark plugs and wires. I just bought the truck on Oct. 30 and it has 60,000 miles. They were really pushing the replacement of the plugs and wires when I was talking to them since it is recommended at 60,000 miles.
The parts guy was telling me that the Hemi use a double copper plugs because they do not run as hot. When I asked him about platinum plugs he told me that Dodge wants double copper plugs for some reason but he could not say why. He also tried to tell me I need to do it because it could damage the engine and Hemi's are very expensive to tear into. The service guy told me that he did not know where the parts guy was getting his info. They told me that it would be about $350.00 for the plugs/wire and labor total and that it was quite the job. They also told me that another Hemi in there had pushed the plugs to 62,000 and they were shot.
I then stopped by a local private mechanic and was asking him if he had worked on the Hemi and he has not. He found it very hard to believe that the Hemi could not take platinum plugs and that it was just a money maker for Dodge. We pulled one of the plugs, I think they are the originals, and it looked good and so did the wire. The wires are still the originals by the date stamp on them.
Has anyone had any problems with the plugs going bad every 30,000 miles or wires? Has anyone heard if you have to use the double copper and not the platinum and why if so? Just wondering if anyone knew Dodges thinking
This is the first Dodge I have owned in about 14 years. I love the truck so far and it is still running great.
Thanks for the help
