Champion iridium. Champion makes the Mopar plugs. It's the closest thing to the original plugs without having to spend $30/plug.
Within the last 8,000 miles New spark plugs
Check out getting rs3 spark plugs if it’ll work.
We changed that spark plug and the customer was happy with the magneto drop. That spark plug worked fine on a Champion spark plug bomb test.
Champions quiet redesign of their plugs to match Tempest made up my mind. It matters, and Champion is just trying to save face.
I have measured resistance above 5k and determined the plug to be causing a problem. Typical resistance is 1-3 kOhm, sometimes less for a new one.
Like everyone has mentioned just go back with an ac delco plug. I ran champions and had Mis fires, none of them were gapped right out of the box.
Avoid Champions. Use NGK or Denso. Don't go cheap on plugs because the job is labour intensive.
Side note, Champion spark plugs suck. Use them in lawn mowers.
Champion is shit for cars. Leave it for mowers and weed eaters.
