丰田雷克萨斯铱金火花塞 FK16HBR-J8 90919-01286 直接替换火嘴

This replacement uses iridium tip electrodes; about 3x burn resistance improvement over nickel-alloy OEM plugs; maintains stable gapping and resists carbon buildup over time. OEM 90919-01286 corresponds exactly with FK16HBR-J8; fits most Toyota/Lexus models from 2000 onward, such as Camry, Corolla, ES. Improves ignition timing and cold-start, especially for high-compression engines. Installation difficulty: medium; use a 16 mm spark plug socket; torque recommended 25-30 Nm; avoid overtightening that damages cylinder head threads.
