About the NGK Iridium IX Spark Plug Line

The Iridium IX Spark Plug line from NGK is designed to provide enhanced ignition performance through the use of a fine iridium center electrode tip. This design improves spark efficiency and durability compared to conventional plugs. The 7510 part number within this line features a copper core center electrode and a tapered ground electrode tip, balancing conductivity and wear resistance for secondary ignition systems.

Technical Details and Specifications

This spark plug features a 5000 ohm resistance to reduce electrical noise interference, making it suitable for modern ignition systems. The single ground electrode with a taper cut tip ensures consistent spark delivery. The plug has a thread diameter of 18.00 mm and a reach of 0.429 inches, with an insulator height of 60.00 mm. The manufacturer heat range is 5, suitable for a variety of engine operating conditions. The non-removable nut terminal type ensures a secure electrical connection during installation.

Applications and Problem Solving

• Compatible with Ford Bronco, Mustang, F-150, and other Ford, Lincoln, Mercury models
• Helps resolve misfires and rough idling caused by worn spark plugs
• Improves cold start performance and throttle response
• Reduces fouling and electrode wear in secondary ignition systems
• Supports stable combustion for better fuel efficiency

Installation Notes and Tips

Ensure the spark plug gap is set to the specified pre-gap size of 0.040 inches before installation. Use a 13/16 inch socket for proper tightening to avoid damage to the tapered seat. Verify compatibility with your vehicle’s make and model, including Ford, Lincoln, and Mercury vehicles such as the E-150 Econoline and Continental. Avoid over-tightening to maintain proper sealing and prevent thread damage.
