Could be intake gaskets too,very known for blowing out and will cause a miss.For plugs,stay away from Bosch and stick with Champions.Chrysler products run like crap with Bosch plugs and Bosch products are junk.Stay away from plugwires from AutoZone,they sell the cheapest garbage out there and I have seen it.My father replaces lot of plugwires from AutoZone to top of the line CarQuest plugwires and I have seen him do this because of a miss or runs like crap.
