五十铃点火线圈AIC4021B 高能点火

Isuzu ignition coil AIC4021B directly mounts atop the engine cylinder head, converting low voltage to high voltage to drive spark plugs and ignite the mixture; key component for starting and running the engine. OEM number 8980895960; fits D-Max, MU-X and other 4-cylinder diesel or petrol engines. Installation difficulty medium; 0.5-1 hour; mind high-voltage loom connections and bolt torque. If idle jitter, weak acceleration, hard starts, or engine warning light is on, coil may be aging or failed; replace promptly.
