WE're over due for plugs also. Has anyone tried those E3(I think that's the name) plugs?

Why are these changed at 30,000? I was under the impression that most plugs are supposed to last for 100,000 miles.

Same question. I just passed 40,000 and the car starts like new and runs as strong as ever.

I just went with the stock plugs. I like to use the KIS model "keep it simple"

Why do these plugs need to be changed at 30,000 miles? The ones in my '00 Ranger and '01 Sable are changed at 100,000?

I believe the SRT's and V6's show that they go 100,000 miles between changes. The owner's manual shows that RT's need to change plugs every 30,000 miles. The only reason I can think of is due to the MDS 4 cylinder deactivation.

Check your current gas millage before and after, I think the early change is gas millage driven not necessarily driven by a performance you can sense outright.

We just had our plugs changed at the dealer. I asked the service advisor about this. The only explanation he could give me is that the 5.7's don't use platinum plugs. Evidently the 6.1's and 3.5's use them.

Yep, the reason is the non-platinum plugs. Which is fine with me, since nitrous does not like a platinum plug. :driving:

everyone hears iridium and platiunum and thinks it must be better.....

not the case, regualar copper plugs provide the best spark out of any plug, only thing is that they have about a 30 to 40k life span.people dont like that and want a 100k plug, only plugs rated at 100k is platinum
