all there is to a "tune up" is a plug replacement. this engine uses coil over plugs, so you don't have ignition wires. just make sure you get the NGK laser iridium plugs the engine calls for.

 

Well, you don't have any sparkplug wires. Individual coils sitting right on top of each spark plug.

I'd just get new stock plugs (NGK or Denso). "Upgrade" plugs normally won't do anything unless you have enough actual engine modifications to require different plugs.

If you've got somewhere in the neighborhood of 100k miles, maybe think about adjusting the valve-lash.
