Product Details and Specifications

This ignition coil operates at 12 volts and is designed specifically for distributorless ignition systems, which are common in modern vehicles like the Ford Fusion and Mercury Milan. The coil-on-plug (COP) type allows for a compact and efficient ignition setup by delivering high voltage directly to the spark plug. The coil features blade-type terminals with two terminals, ensuring a secure electrical connection. The connector is female, while the terminal gender is male, matching OEM specifications. This coil is not oil filled, which is typical for COP ignition coils, reducing maintenance concerns. Note that this part does not include a mounting bracket.

Common Applications and Issues Addressed

• Replacement for faulty or worn ignition coils in Ford Fusion and Mercury Milan
• Resolves engine misfires caused by weak or inconsistent spark delivery
• Improves engine starting reliability in distributorless ignition systems
• Addresses rough idling and poor acceleration linked to ignition coil failure
• Helps restore proper ignition timing and combustion efficiency

Installation Notes and Tips

When installing the NGK COP Ignition Coil 48725, ensure the vehicle is turned off and the ignition system is cool to avoid injury. Disconnect the battery before removing the old coil to prevent electrical shorts. Verify the connector gender and terminal type match the vehicle’s wiring harness. Since this coil does not include a mounting bracket, use the existing bracket or mounting points on the engine. Properly seat the coil on the spark plug to ensure optimal performance and avoid misfires.
