IX Spark Plug

The NGK Iridium IX spark plug LZTR6AIX-13 is engineered for the demands of high-performance engines. Its fine wire center electrode, made from an iridium alloy with an extremely high melting point, ensures a consistently stable spark and high durability. This construction is ideal for today's advanced engine technologies. The plug incorporates several design features for optimal performance and longevity. Trivalent metal plating offers superior resistance to corrosion and seizing, while corrugated ribs are integrated to prevent flashover. The insulator is made from pure alumina silicate ceramic, providing enhanced strength and efficient heat transfer. Additionally, a copper core facilitates heat removal, and triple seals are implemented to prevent any leakage. Key specifications include a 14mm thread diameter, 1.25mm thread pitch, and a tapered seat. The reach is 25mm (1 inch) with a 5/8" (16mm) hex size, and it features a solid terminal type. The gap is set at .050" (1.3mm). The center electrode is a fine wire iridium type measuring 0.6mm, while the ground electrode is a standard nickel type with a taper cut shape. This plug is a resistor type with a value of 5k Ohm and has a heat range of 6. This NGK Iridium IX spark plug is compatible with a wide range of vehicles, including various models of the Dodge Ram, Ford F-150, Chevrolet Silverado, GMC Sierra, Jeep Wrangler, Jeep Grand Cherokee, and Chrysler 300C. It is designed for longevity, with an estimated lifespan of 50,000 miles. Torque specifications vary depending on the cylinder head material: 10.8-18 lb-ft for cast iron and 7.2-14.5 lb-ft for aluminum.
