NGK COP Ignition Coil Stock # 48726

The NGK COP Ignition Coil Stock # 48726 is a direct coil-on-plug (COP) ignition component designed for drivers and mechanics who demand reliable engine performance and consistent cold-start capability. This precision-engineered coil pack mounts directly atop individual spark plugs, eliminating the need for traditional plug wires and distributor systems. Whether you're maintaining a daily driver, restoring a classic build, or troubleshooting ignition misfire issues, the NGK U5076 provides the dependable spark delivery that modern fuel-injected engines require for optimal combustion efficiency.

COP ignition coils function by converting low-voltage electrical input into the high-voltage spark needed to ignite the air-fuel mixture in each cylinder. NGK's coil design incorporates robust insulation and precision winding to handle repeated thermal cycling without degradation, a critical factor in engine bay environments where temperatures fluctuate dramatically during extended driving. The compact form factor—measuring 2.85 x 2.8 x 8.35 inches and weighing just 0.61 lbs—allows for tight engine compartment fitment while maintaining the electrical integrity needed to generate reliable ignition events across the RPM spectrum. Quality NGK coils are engineered to resist voltage breakdown and carbon fouling, ensuring consistent performance in both stock and modified powerplants.

Mechanics and enthusiasts choose OEM-quality NGK ignition coils when replacing failed units or upgrading aging ignition systems prone to misfires, rough idle, or starting difficulty. The NGK COP Ignition Coil Stock # 48726 is an excellent choice for precise vehicle applications—verify fitment with your engine's specific year, make, and model before installation to confirm direct compatibility. Proper installation requires disconnecting the battery, removing the defective coil, and seating the new unit firmly onto the spark plug terminal; no special tools or wiring modifications are necessary on most vehicles equipped with COP systems. Regular coil inspection during spark plug service helps catch early wear and prevents the compounding issues that arise when ignition coils begin to fail.
