Sort of depends.
Stage 1; + 15-20HP
BOV; I don't believe it adds much of anything power wise, but may help with prolonging turbo life
Intake; sort of depends on the intake. Only dyno numbers I've seen for one specific to the PT was the one we did on my car with Adam's full Intake/Uppercharge kit. + 30HP & 14 lb-ft at the front wheels. Others make claims of "up to such and such" but the big numbers are usually reserved for high HP, or high displacement, motors to begin with
Wires; sort of depends on the brand. not sure the wires alone will net you much but in combination with other ignition bits you might gain a bit.
