别克君越昂科威威朗科鲁兹1.5T高压包12635672 点火线圈稳定输出

If your Buick LaCrosse, Envision, Verano or Cruze 1.5T experiences idle wobble, sluggish acceleration, abnormal fuel consumption, or engine warning light, this typically indicates aging high-voltage packs (ignition coils) causing insufficient ignition energy or intermittent misfire. This part, when functioning normally, converts low voltage to high voltage to ignite the cylinders’ air-fuel mixture, ensuring smooth engine operation and power delivery. OEM number 12635672, also compatible with 12670053 and 555692530A, for 1.5T four-cylinder engines in the above models. During installation, use OEM-standard bolts and sealing gaskets, ensure the coil contact with spark plugs is clean and oil-free to avoid secondary faults from poor contact.
