Kit has all the standard tune up parts and some extra stuff:
We include  ignition coil insulator boots as they  get exposed to extremely high temperature and loose their function as an insulator between the engine and the ignition coil. The  Ignition impulse  that is generated by the coil will jump the gap between the cylinder head and the ignition coil causing engine misfire.
Replacing the insulator boots  makes big difference in the engine performance
