Iridium Power Spark Plug

The Denso ITV24 Iridium Power spark plug is engineered for enhanced ignition performance with its advanced design. At its core is a 0.4mm iridium-tipped, laser-welded fine wire center electrode, which significantly lowers the voltage needed for a strong spark. Construction details include machine-rolled threads to ensure effortless installation and removal without seizing or cross-threading. The spark plug is 100% pre-fired to guarantee the highest quality. Its purified alumina powder insulator offers exceptional strength and thermal conductivity, while a five-rib insulator design prevents flashover. A copper-glass seal ensures a gas-tight bond between the center electrode and insulator, maintaining integrity under demanding conditions. Key specifications include a 14mm thread diameter with a 1.25mm pitch, a tapered seat, and a 25mm reach. The hex size is 5/8" (16mm), and it features a solid terminal type with an ISO overall height. The pre-set gap is .031" (0.8mm). The ground electrode is made of nickel with a U-Groove type and a taper cut shape. It is a resistor plug with a value of 5k Ohm and a heat range of 24. Recommended torque specs are 7-15 lb. ft. for both cast iron and aluminum cylinder heads. The expected longevity is approximately 30,000 miles with a 12-month warranty. This spark plug is specifically listed as compatible with 2002-2004 Ford Focus models across various trims (LX, SE, SVT, ZTS, ZTW, ZX3, ZX5).
