Is it still 30 K miles for my 2010????? Or has it been increased???

 

Still the same cause they come from the factory with fast wearing coppers. Which reminds me, I need to climb on top of the ole'engine here soon.

 

What plugs should I install to have a change interval???

 

I don't think I'd call them fast wearing, both sets I've replaced so far had almost no wear on them. As for which plugs to use, I just stick with the factory ones - NGK.

 

I meant relative to the platinums and iridiums. The stock plugs are no worse then plugs have been for decades and they work fine. As a matter of fact, mine have over 40K. I still just check them and change them when they are worn. My last Ram went 55K. I also will use the stock copper design. Although, I wish I had one of those creepers that extends over the engine bay. That would make it more comfortable. A couple different sockets, swivels, extensions, a rubber hose, and a tq wrench.

 

FYI. Spark plug change 0n 2014 5.7s is now 100,000 miles.

Yep, 'cause they are using platinums or iridiums now aren't they?

 

I did mine on my 06' at around 67k if i recall. They looked fine and their was no discernible difference in idle smoothness or power after i put new ones in. So while Dodge may call for 30k intervals you should be no means be scrambling to to it right at 30k. My 2011 is getting ready to turn 50k with the original plugs and ill probably do them by 55k.

 

Yeah. I'm guessing you're right.


The regular copper core plugs ran fine in my 2010, and most guys I talked to with Hemis say they typically go 60K easy. Although I wouldn't take them far.


I know the 100K plugs are going to cost me more, but changing them out is not a pleasant job for an old guy like me with short arms, a weak back, and too much belly.

I have had the change of plugs quoted to me as 2 hrs of shop time, $198 + $96 for the plugs + 15% taxes. $345. Maybe I'll change the easy ones and take it to the shop for the last 4 behind the master cylinder.
