Upgrading Coil

[Quick_Shifter]

I remember reading threads a few years ago about not needing the MSD ignition coils in the pre 20xx trucks because upgrading to the 20xx trucks the coil packs output more. I can’t find that thread and since my 2012 recently turned 60k I want to change/ upgrade the coil packs. I want to say the upgraded coils were the 2015+ trucks but wanted to clarify before I place an order.
Any cons to running the MSD vs the oem.
I have no power adders, just the basics, custom tune, shorty headers, cai, efan, 180 stat

The new coils from the dealer are the upgraded coils.The coils were upgraded in late 2013 when they started using irridium plugs.The MSD coils aren't as good as the factory coils,the factory coils are good to over 1100 horsepower

Im glad I have a 2012, I can run my cheap Champions 446 it would be a downgrade to swap them out... lol.

Factory coil pack are perfectly fine. Trust me I would of swapped them out if they weren't lol...

Copper plugs are actually a better plug then irridium plugs when it comes to making horsepower ,lol. I run nothing but copper plugs in both the wifes 6.4 Challenger and the truck

Do you recommend sticking with an oem coil for 2012?

Thank you. So I want coils from 2014+

As far as i know,if you buy a new Mopar coil now,it's automatically the newer upgraded coil.Doesn't hurt to tell whoever you're buying them from,that you want coils for a 2015 though

I would,they're a high quality coil.

Thank you I’ll call the dealer using a vin from one of our customers trucks I’m pretty sure I have an 18 there

You Can still run copper on the newer trucks. They just don’t come that way for maintenance reasons. I may swap mine to copper and just swap every 30,000 instead because copper hold spark better. Iridium just last longer because it’s a harder metal but has higher resistance than copper so takes more energy to spark
Edit: apparently the iridium fine point tip is there to help promote spark which actually makes them near equal to copper plugs. That’s interesting. Guess I’ll keep my iridium’s.

I could always pm you my vin if you want.

That just confirms the dealer gets it right. Unfortunately my account with the dealer is better pricing otherwise I’d be ordering from Benny @AllMoparParts.com

A bolt on truck won't notice much differance with copper plugs,it's not till you start spraying them with nitrous or are running 7+lbs of boost that you should be swapping to copper plugs Khris,but a header/cam/intake / basically a bolt-on style truck will be good with irridiums

I know. Mines a 17 which is why I offered.

Good point. I don’t plan on going forced induction on this engine anyways. May after I do the bge swap but that won’t be for a long time anyways.

The 6.4's use a differant plug,so that'd be the time to swap to copper plugs,lol

I rather change cheap plugs out every 2 years, specially in the rust belt up here. Literally take an hour to change them out so I dont see any reason to use iridium.

I just want to change my coils my plugs are good. Truck just turned 60k but is 10 years old so I feel better replacing all 8 coils.

 

[DILLIGAF]

My understanding is coils either work or they dont. So Ill change mine out when they crap out. I just keep 1 spare on hand for diagnostics purposes.

I might also be out to lunch. So much info gets posted all the time its hard to keep track.

I’m a maintenance **** many people don’t understand why I do what I do. Most think I’m wierd for religiously flushing my brake fluid.

I’ll have 8 working spares for diagnostic purposes

More of a concern with old trucks (old in years) is the degrading of the plug and coil wires over time. Easy to check them out with a cheap VOM as there is a Ohms spec that they need to meet. Too much resistance from a single one of the wires will cause problems with electronic ignitions.

A higher output coil may compensate for a time but better to deal with the problem at its source.
