RE: need to know what apart is called
My '95 SOHC doesn't have one... I looked, even pulled out the FSM and found everything that had a green wire with a white stripe... Looks like that's a red stripe to me though, which means it's tied into the ASD relay output. Capacitor makes perfect sense, smoother power to the injectors, O2 sensors, coilpack, and whatnot. Good find spud!
