100% what was said above....
these cars are very fussy about plugs and wires.
NGK basic copper core plugs at the proper gap are all it needs, anything else is a waste of your money.
Wires should be either OEM or NGK only... again, anything else is a waste of your money and will fail prematurely.
replacing stuff randomly is bad practice.. you need to figure out what the problem actually is before throwing parts at it.
