NGK COP Ignition Coil Stock # 48978

The NGK COP Ignition Coil Stock # 48978 is a direct-fire coil-on-plug (COP) ignition system component designed for modern gasoline engines that have moved away from traditional distributor-based ignition systems. This compact coil is engineered to sit directly atop individual spark plugs, providing a direct high-voltage connection to each cylinder. It is particularly beneficial for mechanics and engine builders seeking reliable performance in various driving conditions.

The NGK COP ignition coil is constructed with high-temperature epoxy insulation and durable internal windings, ensuring it can withstand thermal cycling and electrical stress over thousands of ignition cycles. Its design minimizes energy loss by delivering voltage through the shortest possible path, which enhances spark rise times and improves combustion efficiency. This results in better cold starts, smoother idle quality, and consistent performance.

This ignition coil is ideal for vehicle owners experiencing misfires, rough running, or weak acceleration, especially in vehicles equipped with COP-style ignition systems from the 1990s to the present. Its compact size allows for easy integration into tight engine bay spaces without requiring modifications. The NGK COP Ignition Coil Stock # 48978 is a reliable choice for enhancing engine performance.
