NGK Ignition Coil U5101 48317

System Requirements Number of Inlets / Outlets: 1 Number of Poles: 3 Port Type: SAE Product Description The ignition coil is an essential part of the ignition system. Due to the high demands placed on ignition coils, the NGK design and the materials used ensure the coils are resistant to the severe heating, cooling and vibration conditions within the engine bay in order to function reliably. Handling high voltage (10,000 V to sometimes in excess of 30,000 V!) is the task an ignition coil must perform reliably. Weak ignition coils cause engine misfiring and performance problems. As one of the world’s leading ignition specialists, NGK offers an extensive range of ignition coils accurately engineered for a precise fit and perfect durability. Although ignition coils are generally very durable, they are wear parts so need to be checked regularly and replaced if necessary. For vehicles with several individual coils, it is recommended to replace not just the defective ignition coil, but the entire set. Fit NGK and don't get stranded.
