I put Autolite APP5325, double platinums. The parts place didn't have NGKs and these had a rebate. I have p0300, p0301, and p0306 on my dash and I think the spark plugs are the culprit.

What is everyone elses experiences with what plugs?

I have only ran the OEM Mopar branded NGKs, and have never had an issue. I would use nickels, so either NGKs or the Champions Burkdadhemi suggested. IIRC Champions used to be the OEM plug in the Hemi

Is it ok to run Platinum or iridium plugs in a 2013 5.7 Hemi, RAM 1500 4x4? Hate to have to change copper plugs every 30,000 mi.

Your truck probably has one o those two from the factory, no copper plugs in yours.

yours came with Copper plugs
the reason for that is because the platinum & iridium spark plugs tend to burn out the coil packs

then they must have made some changes because

Beginning with the 2014 Ram 5.7L
Original Equipment Is Iridium; with Dual Spark Plugs

'That didn't start until 2014, he has nickels.


Pretty much every spark plug has a copper core, some have an iridium or platinum plating, and others are covered in nickel

Mechanic just put iridium platinum in my 2013 Hemi. Do I need to be worried about my coil packs?
They work OK for some people, but if it starts running rough or giving you misfires you know where to look first

As Thunder said, just keep an eye on it. But there is no such thing as "iridium platinum," its either one or the other. I don't recall ever seeing a combination plug. Iridiums conduct a bit better than platinum, so iridiums might be OK. If he used platinums, I bet you'll get misfire codes (or some sort of check engine light) sooner or later.

With our trucks being so computerized these days, and components being so specific with tolerances, its best to stick with the same type of plugs it came with from the factory. Autolite, NGK, Champion, etc. all make decent copper plugs.

Also, as others have said, if you push platinums on a 2013 or earlier, you may have problems with your coil packs later too.

The following year, they installed them in the 2014 5.7L engines

Dual Plug; Gap 0.044"; Actual OE Part

The coil was a
NGK 48716 {#U5121} NGK COP

It's plug change time on my '13 RAM and I noticed that RockAuto sells the NGK LZFR5C11 for $2.95 vs. $5.52 for the Mopar SPLZFR5C11. Anyone have any reason to use the Mopar over the NGK?

Mopars are NGK so I'd say no

Thanks. I was thinking the same thing. Sometimes you hear that parts are made to mfr. specs and the OE part is better than the store shelf stuff but in this case I think I'll save myself some $$$ :smileup:

Mopar spark plugs just put SP in front of the actual plug number of the manufacturer

Like the original plugs are made by NGK
the number NGK uses is LZFR5C11
Mopar just adds on the SP to the LZFR5C11 = SPLZFR5C11

Did those iridium plugs work out fine, or did you have issues.......Just curious, as I am about to change mine.
I know that iridium plugs are mainly made for high performance and long lifetime (good for 100,000 miles), but I heard that some cars with originally installed plugs of other materials might encounter problems because they are "programmed" to run only on their original materials, but I don't really believe that......anyway, if possible, you can try the iridium plugs and if you faced problems, you would know where it came from. But keep in mind the condition and price of the plugs, as ones sold online might be cheaper than those sold face-to-face with the seller, and you may buy used ones from amazon or something if you just want to try them, like these:
