The NGK spark plug wire set for Ford Focus (2000–2004) uses ultra-low resistance mag-core cables to support stronger spark transfer and reduce EMI/RFI interference. High-temp silicone outer jackets with EPDM/silicone inner insulation provide dielectric strength and heat resistance. Stainless-steel winding over a ferrite core, glued boots with silicone sealer, serrated crimp terminals and a corrosion-resistant locking C-shaped spring clip help ensure secure connections. Supplied as 4 wires (coil lead not routed). Limited lifetime warranty; see package for details.
