福特福克斯/翼博/福睿斯点火线套装 1S7G-12286-AE 四线分火线，原厂替换品质

If Ford Focus, Fiesta, or Mondeo experiences idle vibration, weak acceleration, noticeably higher fuel consumption, or check engine light on, ignition wires may be aging, causing high-voltage leakage or increased resistance and failing to transmit ignition energy effectively. This ignition wire set, when functioning normally, precisely delivers high-voltage from the coil to the spark plugs to ensure complete combustion. OEM 1S7G-12286-AE, compatible with Ford Focus, Fiesta, Mondeo and other models, OEM replacement quality. During installation, replace by cylinder order and ensure all connectors are fully inserted into spark plugs and coils to avoid looseness, poor contact, or misfires.
