日产尼桑 点火线圈 AIC-2A08N 替换224481LA0B UF677 原装位

If your Nissan vehicle shows idle instability, sluggish acceleration, check engine light, or cold-start difficulty, this usually indicates ignition coil aging or internal short, causing insufficient ignition energy or intermittent misfire. This coil converts low voltage to high voltage to accurately ignite the air-fuel mixture in cylinders, ensuring smooth engine operation and complete combustion. Compatible with OEM numbers 224481LA0B, UF677; fits multiple 4-cylinder Nissan models (e.g., Sunny, Tiida, Versa). Installation must be done with power off; unplug and reconnect high-tension wires in OEM order; ensure bolts are torqued evenly to avoid poor contact and secondary faults.
