Spark plugs

[Mishalnr]

So guys i saw the oem spark pligs price its really expensive for a spark plug its 250$ fo a set if 16 ! I tried to find NGK spark plugs for the 2014 ram hemi but i couldn't find it in their website only coils and oxygen sensors if any one tried diffrent spark plugs (not mopar) let us know .

If you look on the right hand side. Look for "Moe's Performance" under vendors.

Then on that website. click under Dodge Ram 2009-2016

click under "Ignition Systems"

$80 for 16 Mopar plugs.


I would put a direct link, but I'm not sure if this site gets credit for going through the vendor lists.

No idea for NGK's; sorry

Before you go changeing plugs note that the 14s have iridiumn plugs and they are a 100k plug not 30k

Like previous post....check your owners manual to see not only the type of spark plug, but the service interval. 2013+ models changed even though the engine is the same.

P.s. I got my spark plugs from moes and I could be happier. My truck is a 2012...and I spent $80 and I replaced my own. It took me 3 hours (I took my time and bought the right tools and it was the first time). But I saved over $300 doing it myself compared to the dealer. All it took was time.

The 2014 also has different coils along with the different plugs.

That's the first I've heard if them having different coils. Any proof to this?

The 2012 are different from the 14

I dont have an owners manual so thats why im asking but i know the right mopar part number and im not worried about it because im only at 16 k km and the spark plugs needs to be changed at 100k

Its not the first I have herd of it but I can't confirm pn's speculation is they changed the coils to handle the iridumns.

Just fyi the 100k is miles witch would be about 160km right? And the iridumns are a Damn expensive plug like 10+ per each in the US I'm asumeing sense your in km your in Canada and arebt parts more expensive up there?

Go here, at the top where it says "owners" the drop box will let you download a copy of the owners manual and service manual.

AllPar had an article a few years ago about the ignition and coil pack changes that came along with the Iridium plugs. It was more than coil packs (maybe it was something about the cross over wiring), however. I believe you will find the 5.7 coil pack part number changed about the same time as the plug change over. It did on other vehicles. I think the 6.4 has had iridiums for a long time.

Its been discussed on a number of Hemi related forums. You may think its just spark plugs, but the 5.7 is on the hairy edge of meeting EPA standards, pushing the envelope so to speak. The spark has to be carefully formed for drivability and emissions, and Iridiums have different characteristics than copper.

The Iridium plugs typically use a fine wire center with higher resistance. The coil pack needs to have a higher output voltage to fire the plugs.

Stock plug center copper conductor is thick and its easy for current flow.

The newer motors should use the iridium and have 100,000 mile service intervals. Be prepared to break something trying to get them out

Older motors, real world, some don't care, some protest. There are production variances. So you won't know until you try them. If the engine came with copper plugs, it seems safer to replace with copper and swap them out every 30,000 miles or so. But its not clear cut IMHO

No im in saudi arabia our dealer charges waaay to much like for an 8speed trans oil change is 1500$ ! And 10 k service is 180$ and the 40k and 50k is 800$ ! the spark plugs only here is 320$ For a set of 16

8 Speed oil changes are expensive anywhere, approaching $1000 US.

That could be why some people have tried iridium plugs in 09-12s and had issues.

Wonder if we could get a P/N of them and see if there different and could swap them on the older 4th gens with iridium plugs.

This comes from a neighbor who is a long time Dodge mechanic. He says to always use OEM spark plugs as he has had countless number of times where people did tune ups with new plugs and then their car/truck started running rough.

Factory plugs in my '11 are iridium ones. Got 16 NGK LZFR5C-11 iridium plugs at carquest for $96. Parts guy there said in their computer recommended interval is 80k. According to the carfax service records plugs were changed on mine at 30k and I just did them at 100k and could feel a difference. I know they were changed at some point because I pulled out NGK LZFR5C-11 plugs and I know that's not what the factory uses.

Hate to break it to you but the lzfr5c-11 are a Copper plugs and ngk are factory it's what's in the owners manual and in the Chilton I have also.
