Ignition Coil Packs

[Brad the Ram Man]

Just wondering if anyone is running MSD Blaster Coil Packs (Red) or Accel SuperCoils (Yellow) on their stock 5.7 liter Hemi? Did you notice any difference in performance? How about plug life or gas mileage?

Does your truck call for the older 30,000 mile copper style plugs ,or the newer 100,000 mile iridium plugs.If your truck is a mid year 13,there's a good chance it'll use the newer style iridium plugs.If it does your stock coils are superior to the aftermarket MSD or Accel coils.If your truck uses the older copper plugs,upgrade it with new OEM coil packs for a 2014.When they went to the iridium spark plugs the OEM coils also got upgraded,and are hard to beat
