Jeep is coming up on 100k miles. Manual says to change the spark plugs. Does it make sense to replace the coil packs while at it? If so, with OEM or maybe MSD?

I would only replace them if one is faulty, and only the faulty one.Jeep is coming up on 100k miles. Manual says to change the spark plugs. Does it make sense to replace the coil packs while at it?
