日产蓝鸟天籁轩逸铱金火花塞 22401-CK81B PLZKAR6A11 点火升级优选

When your Nissan Sentra, Teana, or Sylphy experiences idle jitter, acceleration loss, obvious fuel consumption rise, or cold-start difficulty, it usually indicates aging or heavily carboned spark plugs with reduced ignition efficiency. This iridium spark plug can precisely ignite the air-fuel mixture, ensuring smooth operation, strong power delivery, and reduced fuel consumption and emissions. Compatible with OEM numbers 22401-CK81B and PLZKAR6A11 for post-2000 Nissan Sentra, Teana, Sylphy, and other models. Installation requires torquing to specification with a torque wrench to avoid over-tightening and damaging cylinder head threads; ensure electrode gap matches engine requirements.
