日产天籁 新阳光 点火线圈 22448-EY00A UF617 直接替换装

When your Nissan Altima or Sunny experiences acceleration jerks, rough idle, check engine light, or cold-start difficulties, it is typically due to aging ignition coils or insulation breakdown, causing insufficient ignition energy or intermittent misfire. This ignition coil replaces the coil with the ability to convert low voltage to high voltage to correctly ignite the air-fuel mixture and ensure smooth power output and stable fuel economy. OEM number 22448-EY00A; compatible with Nissan Altima (V6 6-cylinder) and Sunny models. Installation must be done with the vehicle cold, disconnect the battery negative, and replace by cylinder order per the original wiring to avoid confusing the firing order or damaging the connector.
