NGK COP Ignition Coil Stock # 48998

The NGK COP Ignition Coil Stock # 48998 (MPN U5029) is a direct replacement coil-on-plug unit engineered to factory specifications for reliable ignition system performance. This individual ignition coil delivers consistent high-voltage output to the spark plug, ensuring precise timing and complete fuel combustion under all driving conditions. The compact black design integrates seamlessly with OE mounting locations, making it an ideal choice for technicians and vehicle owners seeking verified ignition system restoration.

NGK's reputation in ignition system components stems from decades of OE supplier relationships and rigorous quality control. The COP ignition coil design eliminates traditional distributor and rotor wear patterns by mounting directly above each spark plug, reducing electrical losses and improving spark consistency. At 0.6 lbs and measuring 2.75 x 2.75 x 8 inches, this coil fits standard mounting cavities without modification. Direct OEM specification compliance ensures voltage output, resistance values, and thermal characteristics match the vehicle manufacturer's original engineering tolerances.

Technicians replacing misfiring ignition coils, diagnosing cylinder-specific misfire codes, or performing scheduled maintenance will find this single-coil replacement unit essential for multi-coil ignition systems. Because coil-on-plug architecture isolates each coil functionally, a single failing unit can be replaced without removing or disrupting the others. This design also simplifies diagnostics: if coil condition is suspected, the problem coil can be swapped, tested, and confirmed independently. The NGK U5029 serves as both a direct replacement for failed original equipment and a cost-effective solution for preventive ignition maintenance in modern engine designs.
