- Hemi 5.7
I've recently inherited my late father's 2011 Dodge RAM 1500 5.7 Hemi Laramie Longhorn. It's time to get the nickel plated copper core recommended MOPAR plugs swapped out at 210K.
The owner's manual says squat on what plugs can be used. The dealership only offers the nickel plated copper core recommended MOPAR plugs. I'd hoped to use iridium plugs for their longevity.
I've been reading in many different RAM 1500 forums, where members are responding to posts saying stick to the MOPAR nickel coated copper core recommended plugs instead of iridium plugs in a 2011. My interest in the iridium plugs is that they will have a longer life (100K km? 100K miles? not sure); I'm looking to convenience rather than cost, as I'll be living in a remote area of Ontario and will put many miles on the vehicle between towns and want a long life plug.
I'm reading too that members in different RAM forums are saying there is some problem with the coils when using iridium plugs, resulting in engine misfires in 5.7 hemi engines prior to the 2014 introduction of factory installed coils that came with iridium plugs.
So, some posts say that it's not a problem for a 2011 to have the OEM MOPAR nickel plated plugs from the dealership swapped out for iridiums. Others are saying that it's unwise to use anything that's not the MOPAR recommended plugs that need to be swapped out every 30K kilometres and that they've seen problems doing so. It's confusing to say the least.
I hope to keep this truck running for many years as a memory of my father. Insight into what I should use regarding iridium plugs or not with the original coils in place would be appreciated.
