Iridium IX Spark Plug Product Line Details

The Iridium IX Spark Plug line by NGK is designed to provide enhanced ignition performance and durability through the use of iridium-tipped electrodes. This technology allows for a finer electrode that requires less voltage to generate a spark, improving ignition efficiency. The 6510 part number within this line features a copper core center electrode to further support electrical conductivity and heat dissipation, making it suitable for specific Cadillac models.

Technical Description and Specifications

This NGK spark plug features a single ground electrode with a taper cut tip, crafted from nickel for durability. The center electrode core is copper, which aids in heat transfer and electrical conductivity, while the iridium tip ensures long-lasting spark performance. The spark plug has a pre-gap size of 0.044 inches, a tapered seat for secure fitment, and a thread diameter of 14mm with a 25mm reach. The heat range of 7 is calibrated to match the thermal requirements of Cadillac CTS and XTS engines, helping to prevent fouling and pre-ignition.

Compatible Vehicles and Common Applications

• Replacement spark plug for Cadillac CTS models
• Replacement spark plug for Cadillac XTS models
• Addresses ignition misfires and rough idling
• Helps resolve poor fuel economy issues
• Improves cold start performance

Installation Notes and Tips

When installing the NGK Iridium IX Spark Plug 6510, ensure the spark plug gap is set to the specified 0.044 inches if adjustment is necessary. Use a 5/8 inch socket for proper torque application and avoid over-tightening to prevent damage to the tapered seat. It is recommended to inspect the ignition system components during replacement to maintain optimal engine performance.
