IMO oppinion the OEM ignition works just fine, other than the small diameter cap that is prone to crossfire, when the inside gets dirty from from burnt carbon and oxides from normal wear and tear.
I really don´t know if a kit to increase the diameter of the cap and rotor are worth the money, caps/rotors are cheap and can be replaced often.
A good set of wires sure can´t hurt much, but the coil to cap wire, together with the OEM module, seems a little sensitve to the resistance (ohms) in that cable. I´ve had better luck keeping the coil to cap wire stock.
