现代起亚新款火花塞 18858-08090 ELR9QC8 12×26.5mm 规格

When your Hyundai or Kia vehicle experiences idle jitter, acceleration weakness, higher fuel consumption, or cold-start difficulty, this usually indicates the spark plug electrode has severely worn or carbon fouling and cannot ignite properly. The spark plug should be replaced to restore ignition efficiency. OEM number 18858-08090 / ELR9QC8; fits many Hyundai and Kia models after 2000 (e.g., Elantra, Sonata, Cerato, Sorento, etc.). Use a torque wrench to tighten to specification; prevent over-tightening that could damage cylinder head threads or under-tightening that could cause leaks; also keep the spark plug bore area clear of debris to avoid dropping into the cylinder.
