Spark, plug wire resistance

Spark plug resistance makes a difference also. Case in point. Dodge 5.7 hemi. spark plug resistance in champion from auto parts store is different than plugs from dealer. There is a tsb that concerns 5.7 engines dying at stop signs, with no apparent cause. Mopar says it has to do with the plug resistance difference. Mopar has plugs made to their specs. I put champions from napa in my 08 and it happened. Bought plugs from dealer where wife worked and no problem. Does not affect your concern here but it may bite someone later.
