The iridium center electrode tip offers a fine wire design that improves spark efficiency and reduces voltage requirements. The ground electrode features a taper cut design with a platinum tip, enhancing durability and spark consistency. Copper core construction in the center electrode ensures excellent thermal conductivity, helping to dissipate heat effectively.\u003c\/p\u003e\u003cp\u003eThis spark plug includes a ceramic insulator that withstands high temperatures and electrical stress, while the resistor type with 4000 ohms resistance minimizes radio frequency interference. The XP5863 has a metric thread size of M14 x 1.25, a reach of 0.982 inches (25 mm), and a 5\/8 inch hex size, making it compatible with a variety of ignition systems. The pre-gap is set at 0.032 inches (0.8 mm) to optimize spark timing and combustion efficiency.\u003c\/p\u003e\u003ch2\u003eCompatible Vehicles and Applications\u003c\/h2\u003e\u003cp\u003eThis spark plug is compatible with multiple makes and models, including Buick Regal, Cadillac CTS, Chevrolet Equinox, Ford Mustang, GMC Terrain, Jaguar XF, Land Rover Discovery Sport, and Lincoln MKZ.
