Coil pack

What is the difference between using spark plugs or coil packs ? Is it worth spending the extra $?

You need both for your engine to run. The coil(s) are what connect to the top of each spark plug. It transforms your cars low voltage to the thousands of volts needed to create a spark.

If they aren't bad and you're not having any issues, you don't need to replace any of them.
