2013 RAM 1500 5.7 - Which spark plugs?

[Stringer45]

im reading in places that NGK 92145 (is the way to go, and other areas of forum that say use the copper "mopar" plugs which i assume is the SPLZFR5C11. And that the coil you have may, or may not, come into play when choosing a plug.

my owners manual does say to change out plugs every 30k. am i to assume then that they are copper? id rather not go outside and start pulling things apart until i get the new parts in.

ive seen a few ewtube videos and did not see anyone using a dielectric grease. is using this just not beneficial?

i did order the gearwrench 80546 per advice on threads i came across here.

which plugs should i buy u think? id rather not have to change them every 30k if possible

copper every 30k, if you want 100k mile plugs you need upgrade coil packs, but do those plugs really last 3 times as long? stay where you are at imo, btw see how the plugs are doing many guys can go over 30k.

yes dielectric grease is great, just make sure it only gets on porcelain and not the top of the plug, less is more. Get in on top of plug might misfire. It's all about location and condition of plugs, if plugs are prestine, no need for d-grease. If there is an issue with stray current and pocrelian is burnt up, for sure use it.

Other thing is anti seize, I personally like to use a thin coating on plugs for next time, personal choice.

What ever you do,don't buy plugs off Amazon or Ebay,both places are flooded with cheap Chinese knock-off plugs,either buy from your local auto parts store or Rock Auto. Follow Burla's advice about the di-electric grease and anti-seaze on the threads
