Technical Details and Performance

This NGK spark plug (part number 94806) incorporates a copper core center electrode that enhances electrical conductivity, ensuring reliable spark delivery. The platinum tip on the center electrode improves electrode longevity by resisting erosion. The ground electrode uses nickel core material with a standard design, providing a stable spark path. The spark plug features a 5/8 inch hex size for installation and a 25mm reach, suitable for the specified vehicle applications. The insulator height is 53mm, and the heat range is rated at 6, balancing heat dissipation and performance.

Applications and Problem Solving

• Restores proper ignition in Ford F-150 and Lincoln MKX engines
• Reduces engine misfires in Mazda MX-5 Miata and Ford Mustang
• Improves fuel efficiency and throttle response in Ford Explorer and Lincoln MKS
• Addresses rough idling and starting issues in compatible vehicles
• Supports consistent combustion in Ford Transit series vans

Installation Notes and Tips

Ensure the spark plug gap is set to the factory specification of 0.052 inches before installation. Use a torque wrench to tighten the spark plug to the manufacturer’s recommended torque to avoid damage to the tapered seat. The non-removable nut terminal type requires compatible ignition connectors. Inspect the spark plug threads and clean the cylinder head threads before installation to ensure proper fit and sealing.
