Ignition coils. How often should these be replaced?

Its for a 4.7 ram. I changed the plugs at 108k miles. I was told I shouldn't need to change the ignition coils until they go bad? It uses coils instead of plug wires thanksIgnition coils. How often should these be replaced?
Individual ignition coil replacement is only necessary if the engine starts to skip or misfire. When this happens, generally speaking the %26quot;check engine%26quot; light will flash on. The individual coil prices have dropped recently but there is still no need to replace them unless there's signs of the above trouble.



Ignition coil performance either works perfectly or not at all. Believe it or not, the lower the electrical resistance on the coils, the cooler and longer they last. To keep the resistance as low as possible, change the factory recommended spark plugs when your service book recommends. Platinum tipped plugs are usually good for 50,000 miles. Iridium plugs last 75,000. Regular %26quot;low dollar%26quot; plugs are only good for 25 - 30,000 miles.Ignition coils. How often should these be replaced?
Coil-On-Plugs don't have a maintenance interval. Unless there is a problem - cracked insulation, rubber deteriorated, missfire - they should last the life of the vehicle.Ignition coils. How often should these be replaced?
