How many ignition coils the 3.7L dodge nitro dose have

it has 6,one for each cylinder. i wouldn't replace all of them,they all don't go out at one time. if you replaced #1 spark plug and the coil>> (COP) and you still have a misfire code on #1, then neither one of those are the problem.more testing needed before throwing parts at it! all 6 from RockAuto are $198.63 no tax, verses local parts store for $330.00.
