I posted about oil filters, and got many good responses. One more. I have a 2010 Ram, 5.7 V8. Spark plugs. I have read stay with the stock style, also hear the newer type are better, like Iridium, E3, etc...Any experiences here with these? Thoughts? Thanks

Stay with stock iridium.

The ECM timing algorithm was set using these with their specific internal resistance. Swapping different types of plugs will unpredictability change performance.

No platinum, ruthenium, nickel, unobtainium, or goofy electrodes.

His truck doesn't use iridium plugs,it's old enough it'll still have the earlier coils that call for copper plugs.

Stick with stock plugs,and "Do Not" buy them off Amazon or Ebay,the majority of plugs on both sites are fake knock-off plugs
