Technical Details and Application
This spark plug features a copper core in both the center and ground electrodes, which promotes excellent electrical conductivity and heat dissipation. The iridium center electrode tip provides a fine, durable point for consistent spark generation, while the square platinum ground electrode tip supports high ignitability. The standard ground configuration with a single electrode ensures reliable spark gap maintenance. The non-removable nut terminal type offers a secure electrical connection, reducing the risk of loosening over time.
Common Issues Addressed by NGK 93593 Spark Plug
- Engine misfires and rough idling in Ford EcoSport, Fiesta, and Focus
- Reduced fuel efficiency due to incomplete combustion
- Difficulty starting the engine in cold conditions
- Loss of engine power or hesitation during acceleration
- Increased emissions from inefficient ignition
Installation Notes and Tips
Ensure the spark plug gap is set to the specified pre-gap size of 0.028 inches before installation. Use a 14 mm socket wrench to tighten the spark plug to the manufacturer’s recommended torque specification. The tapered seat type requires proper seating to avoid compression leaks. Confirm compatibility with your specific Ford EcoSport, Fiesta, or Focus model year before installation.
