If you have one coil in a vehicle with 8 coils, how likely will the others go bad if one is bad? Is it better to replace all or some even if just one is bad? What's the most cost efficient thing to do?

The coils are meant to last the life of the engine. They normally do not do this but they only require replacement when they fail. So I would only replace those that are faulty.

Here is a guide that talks a little about this info:

I am attaching the info below on the firing order and replacing the coils. Please run through this material and let us know if you have questions. Thanks
