93220 LKAR7AGP-D 铂金火花塞，骐达轩逸卡罗拉专用点火组件

93220 LKAR7AGP-D platinum spark plug is directly installed in the engine cylinder head; its core task is to precisely ignite the air-fuel mixture to ensure smooth operation and efficient combustion. As an original OEM part number 93220 ignition component, it is designed for 2000s Toyota Corolla, Nissan Tiida, and Sylphy models. Installation difficulty is medium; allow 0.5-1 hour; strictly control torque and electrode gap. If the vehicle shows idle shake, weak acceleration, rising fuel consumption, or starting difficulty, electrode wear or carbon buildup is the likely cause; replace promptly to restore strong ignition.
