Hello,

This vehicle has two coil packs and not wires.
A typical tune will only need to replace the spark plugs. Of course, if the coil pack is failing you will have to replace that as well, but it is not a maintenance item.

I have attached a diagram below for your reference.

Let me know of any questions.
Thank you.
