Spark plugs I do at every oil change, about 3k miles. Coil packs I wouldn't know. Replace them when they go bad

Ditto, I use just plain jane copper 7series ngk's so they are cheap enough to replace every oil change. There's no reason to replace coils as regular maintiance,I'd only replace when they act up, espically at $60+ a pop
