Iridium IX Spark Plug Product Line Details

The Iridium IX Spark Plug line by NGK is designed to provide enhanced ignition performance through the use of iridium, a material known for its high melting point and wear resistance. This line focuses on delivering consistent spark and improved throttle response, making it suitable for vehicles requiring reliable secondary ignition components. The 7164 part number is part of this line, combining iridium technology with a copper core center electrode to balance durability and conductivity.

Technical Description and Fitment

This NGK spark plug features a single ground electrode with a taper cut design, which increases the spark exposure area and promotes better combustion efficiency. The center electrode is made of copper with an iridium tip, enhancing electrical conductivity and electrode life. The ground electrode core is nickel, providing structural strength. With a thread diameter of 14 mm and a reach of 0.708 inches, it fits a variety of vehicles including models from Buick, GMC, Lincoln, and Pontiac. The non-removable nut terminal ensures a secure electrical connection, while the 53 mm insulator height and tapered seat type support proper installation and sealing.
