Nissan Iridium Spark Plug 22401-00Q0K ILKAR7J7G OEM Performance Upgrade

When your Nissan shows rough idle, hesitation in acceleration, cold-start difficulty, or noticeably higher fuel consumption, it often means spark plug electrodes are severely worn or carbon-deposited, leading to insufficient ignition energy. These iridium plugs reliably ignite the mixture to ensure smooth power output and reduce emissions; this iridium spark plug has OEM numbers 22401-00Q0K / ILKAR7J7G and fits many post-2000 Nissan models (e.g., Teana, Sylphy, Tiida). Install with a torque wrench to the manufacturer’s torques to avoid damaging cylinder head threads or leakages from over/under-tightening.
