Sparks plugs

[beep119]

Hi everyone, been trying to find what spark plugs to put in my 2012 Ram 1500 hemi.
Been reading different things, use oem, use platinum, now its iridium....enough to make your head spin.
I don’t remember what was used last time I changed them.
Right now Bosch platinums and NGK platinums are on sale at local auto store. These good?
Thanks in advance!

Subscribed. I really wanted to put in iridium in my 2012 but they said you would need the newer coil on plug packs that work differently than the ones we have for copper.. 2013/14+ years would work.. thats when they switched to iridium. But when I look at the COPs they are the same part numbers for 2012s as they are for 2013s and up.

Any early 4th gen guys go ngk iridium?

Most people stick with the OEM spark plugs. Some people have put the fancy plugs in and have had some problems with their truck not running as good. I think your 2012 calls for new plugs every 30K

My '09 1500 5.7 with 3.92s ran like a ***** ape with the stock plugs. Had a 93 octane tune in it too. No issues ever. Had 110k on it when I traded it in.

Always bring enough gun.

Right the OEM in 2009 to 2012 was ngk copper.

In 2013 they switched to ngk iridium.

Copper is 30k change intervals iridium is 100k.

No changes were made to the engine or ignition system... from 2012 to 2013

So just asking if anyone went with the OEM iridium over copper in the early 4th gens.

I put iridium in my 07 once. Truck ran like crap. Put the copper plugs back in. My understanding is if you change to something other than copper plugs, then you will also need to upgrade the coil packs. This is what I have read at least, never actually did it.

Anyone tried E3 plugs?

My ‘13 came with oem copper plugs. I changed the coil packs to
these and it ran just fine with platinum plugs.

Changed plugs every 20k miles. I'm old. Used to changing plugs every 12k miles or once a year. I let it go to 20k cause they said 30k was ok. Point is, I only used OEM plugs.
