NGK (NGK Spark Plug Co., Ltd.) Ignition Coil Part Number: U5141

Reference OEM part numbers: 22433-AA640, 22433-AA641. The ignition coil consists of a primary coil and a secondary coil, each with a different number of windings. When the current flowing through the primary coil is interrupted, an electromagnetic force generates high voltage in the secondary coil. Previously, the voltage generated by the ignition coil was distributed to each cylinder's spark plug by a distributor. However, direct ignition systems, which do not require a distributor and instead use dedicated coils located on each cylinder's spark plug, are now mainstream. Please check the manufacturer's website for details before purchasing. Images, size, and weight are for illustrative purposes only. Size, shape, weight, and product packaging may vary depending on the model number (product number).
