Default Changing Spark Plugs - 2003 Ram 2500 Hemi

Ok so my truck has over 144k miles on it. I bought the truck used in 2005 and it had 53k miles on it then. I dreaded even the concept of trying to change out the spark plugs due to some posts regarding stripping out the threads and then needing to have the heads drilled/tapped again. Geech that would really suck.

But, I want you all to know that I finally swallowed my fear and dove head first into this project this morning. $60.00 for new plugs - and I stuck with the OEM Champion plugs and one new $45.00 coil pack. 12 hours later, and the job is done - sort of.

I started with the first two plugs on the passenger side and gapped them to .045, installed them, then installed the spark plug boot and coil pack, spark plug boot and electrical connection on the coil pack. Then moved to the next set of plugs and repeated all the way to the drivers side.

I'm here to tell you that the last two sets of plugs under the brake booster is quite a challenge. But be smart, and remove the air bellows on of the engine. There are only two small 3/8" bolts in the front holding it on along with a small electrical connection just off to the left center in the front.

Now, when I got the engine all put back together, I fired up the truck. *lope, lope, lope.....dead...." WTH? So, I checked all electrical connections again and re-sat each spark plug boot again (multiple times) and the truck finally fired up but not without an engine code.

I drove down to the local auto parts store to get the code checked out and it said it was a bad air intake temperature - high temp gauge. But, I haven't changed this yet. I also noticed that there was a small grounding wire on the passenger side of the block that went from a rubber grommet to and looped over the top of a stud. This is located directly on the top center of the valve cover on the passenger side. Thinking this might be the culprit to why the truck was loping and then dying, I changed that out but to no avail. I think I'll try the air temp sensor tomorrow to see if that fixes the issue.

Attached are some pictures of what spark plugs look like that are well worn beyond their use. These should have been changed years ago, but again my fear was holding me back. It shouldn't have because I had absolutely NO issues at all removing them and will keep up with the 30k mileage requirement of changing them like they should be.

The gaps varied in size from .070 to .085 on the old plugs. Quite a bit of difference than what is recommend.

Yeah, those gaps are pretty big! $60 for plugs? Ouch! "Air bellows"? What's that?

I'm a computer guy, so the way I describe parts probably isn't what it should be for an automotive forum.

Air bellows - That dealio above the motor that says Dodge Ram Hemi 5.7L on it. The air filter 4" hose connects to it along with the oil vent pipe.

That's the Hem-Hat and the PCV feed back to the intake. That's the oil filler, BTW. What plugs did you use?

Ha! Hemi Hat... Good name for it.

Right side of the Hemi Hat has an input for the rubber hose that comes off the oil fill. Center of the Hemi Hat has an air temp sensor and the Hemi Hat "plugs" into the throttle body and is secured to the top of the intake manifold with two bolts on the front corners of the Hemi Hat.

Plugs used - Champion Single Platnum #3570 gapped at .045"

That explains the $60. Platinums are not recommended in the Hemi. The plug change interval makes it kinda expensive.

Let the flaming begin.

Damnit! Those were the recommended plugs from Champion's website because I couldn't find Champion #RE14MCC4 plugs anywhere in my town.

"Spud"

While the recomended plug is the copper core Champion, some on this site have stated they had no problems with the platinums. I am interested in the difficultly you experienced in removing the plugs after 8 years and 144K or at the bare minium 90K.

Looking at the plugs, it says alot about the flexibiilty of the control module to keep the motor running. Keeps us advised on how you resolved the current issue. With the hours you put in, hopefully it's not the motor rejecting the platiniums.

The plugs weren't that hard to get out actually. Just the normal push or pull on the ratchet got them out easily.

I'm wondering now too if the Platnum plugs are the culprit in why the engine won't throttle up smoothly.

I guess I'll run these for the week and then change them out again next weekend. I'll have to order the correct plugs online.

spud83672-

You are a better man than I.

A few years ago I was going to attempt to change my own spark plugs. I have a 2500 4X4 that sits pretty high. I am only 5'-7" tall. I took one look to see how far back I would have to reach/stretch and said forget it. I found a Chrysler/Dodge/Jeep coupon, for $89.95, and let my local dealership change them out.

Last month, I was due for another spark plug change (61,000 miles). I got lucky and found another one of those $89.95 tune-up coupons and dropped the truck off at the dealership. The best $89.95 spent (twice)!

How often do you guys change your plugs? Also, what plug do you guys use? I read here Champion says to use a platinum, and someone else said a copper core?

Of course Champion says platinum. If you made spark plugs, which would you rather sell, the $2 ones or the $4 ones?

The book says change 'em every 30K. 40K is probably OK. My C had 49K on the plugs when I changed 'em. I used NGK 5306s on the Ram and the C.

I had them changed the first time at 27,XXX miles. The second time was at 61,XXX miles. I am trying to stick with the 30,000 mile factory recommendation.With aluminum cylinder heads, I do not want the spark plugs in there for too long possibly seizing into the heads. The O.E.M. Champion Copper spark plugs were used both times.

While I do agree that most auto parts clerks are CLUELESS...The recommendations come from the computer system...I just looked at Advance Auto website put in vehicle info and I ONLY use Champion plugs, so I filtered the results and saw the 3570 mentioned in this thread so I clicked on it to get full description and it says these plugs are platinum and will fit your vehicle, but double platinum is recommended...I then read more of this thread and found that the copper plus are the way to go...which excites me some, $30 every 30,000 vs $60

Well I have a body lift and am taking the brake booster out and putting in a hydroboost so for me, changing plugs is a breeze.

...whoever does their homework for the auto houses obviously didn't do it right.. platinums and ram coil packs don't like each other and I know they are teaching this to dealer mechanics now... but again, alot of people still believe whatever the screen spits out...
