Pin-to-Pin Design Iridium Spark Plug 22401-ED71A FXE16HE11 Platinum Spark Plug

When your Nissan shows idle instability, acceleration hesitations, cold-start difficulties or higher fuel consumption, typically spark plug electrodes are aged or heavily carboned, resulting in insufficient ignition energy. This iridium-tip plug designed for Nissan (OEM 22401-ED71A / FXE16HE11) uses dual electrode design to release high-energy sparks precisely, ensuring complete combustion and restoring smooth power while reducing emissions. Fits Nissan post-2000 models such as Tiida, Sylphy, Teana, etc. Use a torque wrench to tighten to the manufacturer’s specified torque; avoid over-tightening which damages threads or under-tightening which causes leaks.
