Has anyone changed plugs on a HEMI yet? if so, is it difficult? I called the dealer and they told me that it should be done every 30,60,and 90k miles.I'm at 39k now ,I don't have problems with my HEMI, just want to get it done. Thanks in advance..:rolleyes2:
Yeah...I was told that I should only need to change the plugs...two plugs per cylinder..just wondering if anyone has done it themselves,and how to do it.
It was under the "How do I...EVERYTHING!" sticky at the top of this section. I suggest always looking there first when you have questions like this because after 6 years of these cars there has been a lot of knowledge accumulated there.
I did it myself when I hit the mileage mark piece of cake and im not a wrencher I just followed instructions found here. Also if you dont want to replace them in another 30k miles put something besides the garbage OEM copper plugs in there.
took me an hour. My buddy did one side and I did the other at the same time. Was the easiest tuneup I've ever done. Now my 2001 Silverado, that was a *****.
Just because the factory put them in does'nt mean its good for the car...they put them in because they are cheap,only last 30k?,come on,they should last twice that.
Thanks for the updates. I've wondered why Dodge uses regular plugs in the 5.7 and platinums in the 6.1. I thought it might have something to do with the MDS. Yea, I need to do ours in 5,000 miles.
My 2007 SRT came with Iridium plugs. Both the 5.7 and 6.1 have the same coils so the platinum and iridium plugs that are standard in the SRT should work fine in the R/T.
I switched from iridiums to coppers after reading all the stories about people having stalling problems with the high dollar plugs. I even had Service Managers at the dealers suggesting that I down grade to the coppers. I took their advice and my car ran worse with the coppers than it did with the iridiums. My gas mileage went down as well. I even tried changing brands of copper plugs and that went even further in the wrong direction.
I would like to see some pictures of the old plugs. personally i think my OEM coppers would have been fine until 60k. I had new ones already bought at 30k so i went ahead and replaced them.
Back in the day, we could easily get 50K out of the coppers. A good engine could get 75K even. We filed down the tip to make them square again and reset the gap. A file and gap tool were in every DIY's tool box.
Those do look good from what I can see, what your really inspecting is the electrodes for wear. My "100K" factory platinums were pretty eroded by I think it was 72K. So, a plugs "usable life" isn't the same as its optimum life.
Well...I didn't want to push it,I want my Hemi to last long ,my mileage is at 39k and I was told to change the plugs at 30k...I already felt like it was overdue.
generally both copper and plat. plugs fire the same but the plats. last longer because the tips are platinum.So they wear down slower.If you see a car with 100,000 miles tune up intervals it usaully means it has plat plugs and that usaully means they are a PAIN to remove.
Side note I just changed my 2000 ram plugs at 86,000,copper.The trunk ran pretty smooth but needed a change and appearntly it was its first change(I bought it earlier this year).The tips were woren down from stck .40 to .60:eek3: but other than a slight stumble here and there it ran fine.
So not changing your plugs won't hurt your motor just uses more gas because they cant burn it all.
If you want fewer plug changes go with the platinums but if you want OEM the coppers work just as good just not as long.
