2010 RAM 1500 spark plugs question

[tincup]

Hey guys, new to the forum. I have a 2010 with the 5.7L hemi, about 134k miles. It's time for me to replace the spark plugs. I've seen conflicting opinions on what the best brand, etc. is. What model no. and brand do I need?

NGK is what MOPAR uses. Just did mine a couple months ago. Moe’s has them here.

Oem works the best.

Thanks guys. I found these on amazon for even cheaper but the Moe’s link looks like what I’m looking for.

Those are the ones. I recommend checking the gap on each one. .043 is what I used. Get some anti seize on the threads and dialectic grease in the boots and you are golden!

Yeah, you have to use those and more importantly replace every 30k. Post up some pics of those old plugs, I might consider coil packs with that much mileage as well. If you put back a different coil pack, you can use 100k plugs, do some research.

Are those the standard NGK plugs? Not Iridium or Platinum, right?

 

[huntergreen]

Correct gordin

I replaced mine 3 months ago with NGK, no issues reported

Just watch those coil boots, and I think the Hemi has 2 plugs per cylinder

NGK standard means copper I assume?

Hello guys,

just a thought of what I’ve done before:
I’ve changed the spark plugs almost 2 years ago on my 2010 Ram 1500 5.7. I worked at Autozone back then and I looked into getting the best plugs for my truck. I looked for longevity, durability of the plug and how often do I changed them. Well, I ended up buying the Denso Double Iridium(around $9.50 each) plugs and they are good for over 100,000 miles.it’s been almost 2 years and way over 100,000 miles that I replaced them and the truck has not given me any issues at all. Love the way it runs smooth and quite. I’m sticking with these same plugs again cause now I see how durable they really are and it’s time to change them out after almost 2 years are coming up since I last change them out. I spent about $150 on plugs alone but I guess it’s not bad when they last this long. We’ve been to New Mexico, Florida and all over Texas and NO ISSUES AT ALL. But yet again, I’ve been working on cars since I was 15 and love my Ram truck.

Go all the way - spend some mo' money and go with the latest - ruthenium! lol Then you can get 1/4 million miles and better spark, too.

In all seriousness, I suppose there is some kind of market for these, but probably only the Japanese companies could come up with something this extreme. American corporations won't anymore.

You actually want to put dielectric grease on the threads. Its to help electrical conductivity as the threaded area acts as a ground. Also, will help with keeping moisture out of the cylinder.

i have done 3 sets with ngk and no issue. if the coils were not so much more plus the cost of iridium plugs i would make the switch

Check out;

https://www.rockauto.com/en/catalog...ckup,5.7l+v8,1445018,ignition,spark+plug,7212

NGK 92174 {#05149177AB, LZFR5C11, SPLZFR5C11} Standard
Dual Plug; Gap 0.044"; Actual FCA OE NICKEL plug (30,000 mi/48,000 km interval).
$ 3.01 each

NOTE: FCA OES now recommends IRIDIUM extended service plug.

NGK 4469 {#BY481LFR5A, LFR5AIX11, MZ602090} Iridium IX
Dual Plug; Gap 0.044"
$ 6.33 each

When you go into an auto parts store the number after the NGK will be the number on the box; ie NGK 9217 or NGK 4469

The number on the spark plug likely may be either LZFR5C11 or LFR5AIX11

If the spark plugs are bought at the dealership it will likely have a SP before the number
SP = Spark Plug
