日产350Z点火线圈 22448-FY500 高压包 直接替换原厂 引擎稳定输出

Is your Nissan 350Z experiencing idle vibration, sluggish acceleration, higher fuel consumption, or check engine light? These indicate aging ignition coils causing insufficient ignition energy or intermittent misfires. When functioning, ignition coils convert low voltage to high voltage to ensure stable spark plug ignition of the air-fuel mixture, maintaining smooth engine output. This product OEM 22448-FY500 fits Nissan 350Z (VQ35DE) and some Infiniti G35 models. Always work with the engine cold and ensure tight contact between coil-pack and spark plug to avoid later faults.
