Spark plug help

[nunyabusines]

I have a 2012 dodge ram 1500,4.7L
Well overdue for all 16 plugs .
Bottom was last changed 2021 and top .. a years or so prior ..

Anyways I can’t seem to find anyone around me who seems familiar with what plugs I need ( with the exception of the dealership who just gives me a price to get it done with them )

I am looking for NGK .
Wondering if I can put the same NGK iridium to plug in both intake (top) and exhaust (bottom) ?
If you have a different reccomendation please let me know

The best thing that I have heard and has worked well for me and my dad is to use whichever plugs came in it.

I think OEM is copper that year. which means coils packs aren't made for iridium's. Now, many guys are running iridium's anyway, so you probably will get away with it as opposed to definitely will get away with copper ngk.

My vote is on copper, too.

I'd say you got yout money's worth out of them.

Keep us posted.

Am I correct my understanding that this would be the correct one I need

• 8× NGK 92174 (LZFR5C-11) for the intake side
• 8× NGK 97606 (PLZFR5B-13EG, Laser Platinum) for the exhaust si
