日产Pathfinder奇骏X-TRAIL 火花塞 22401-8H516 LFR6A11 通用匹配

Does your Nissan Pathfinder or X-Trail exhibit idle jitter, weak acceleration, noticeably higher fuel consumption, or cold-start difficulty? These symptoms often indicate worn or carbon-deposited spark plug electrodes causing insufficient ignition energy. Spark plugs ignite the air-fuel mixture to ensure smooth engine operation and power. This product OEM 22401-8H516 and LFR6A11 fits 2000-and-newer Pathfinder and X-Trail models. Use torque wrench to tighten to specification; avoid over-tightening to prevent thread damage or leaks; check ignition coil boots for aging.
