捷豹路虎点火线圈OE J6P312A366AA替代，LR121788原厂标准，稳定高效

If your Jaguar Land Rover vehicle experiences acceleration hesitation, idle shaking, engine warning light, or even cold-start difficulties, these are typical signs of ignition coil aging or failure. This part normally converts low voltage to high voltage to precisely ignite the air-fuel mixture and ensure smooth engine operation and power output. OEM number LR121788, suitable for many six-cylinder Jaguar Land Rover engines, such as those in Land Rover Discovery, Range Rover Sport, etc. During installation, be sure to use OEM-spec screws and torque, and ensure the ignition coil contact surfaces with spark plugs are clean and free of oil to avoid secondary faults from poor contact.
