NGK COP Ignition Coil Stock # 48991

The NGK COP Ignition Coil Stock # 48991 is an OEM-quality direct ignition coil designed for modern vehicles that utilize coil-on-plug (COP) ignition systems. This high-voltage component replaces worn or failed coils that sit directly atop each spark plug, eliminating the need for traditional plug wires. If you're experiencing rough idling, misfires, or check engine lights due to ignition issues, the NGK U5065 is engineered to address these reliability concerns.

With a compact design, this ignition coil fits the tight confines of modern cylinder heads while maintaining the necessary electromagnetic windings and insulation for reliable ignition. The sealed construction is specifically designed to resist moisture and heat degradation, which are common failure modes in older coils operating in engine compartments where temperatures can exceed 200°F. This ensures consistent performance across various RPM ranges, contributing to clean combustion and improved engine efficiency.

The NGK COP Ignition Coil Stock # 48991 is ideal for vehicle owners addressing intermittent misfires, poor fuel economy, or hard starting, issues that can worsen as coils age. DIY mechanics and shop technicians prefer NGK replacements because they match OEM specifications without the dealer markup. Installation is straightforward, making it accessible for both professionals and enthusiasts alike.
