现代索纳塔2.0 起亚喷油嘴 35310-33150 9250930004 燃油系统升级

When your Hyundai Sonata 2.0 or Kia models have idle jitter, weak acceleration, noticeably higher fuel consumption, or cold-start difficulty, it usually indicates injector atomization degradation due to carbon buildup or wear, leading to uneven fuel spray. The injector sprays fuel into the cylinder with precise atomization, ensuring thorough air-fuel mixing for stable power. This product fits Hyundai Sonata 2.0 and corresponding Kia models, OEM 35310-33150 and 9250930004. Use a new sealing washer during installation; ensure clean rail interface; perform leak testing and ECU calibration after installation.
