Show original supplier description
The Denso ITV20TT Iridium TT spark plug combines advanced material technologies to deliver enhanced engine performance and longevity. It features the world's smallest 0.4mm iridium center electrode paired with a 0.7mm needle-tip ground electrode. This Twin-Tip (TT) design minimizes spark interference and promotes a more concentrated spark energy, leading to more efficient combustion. Denso's patented iridium alloy construction ensures durability, contributing to the plug's extended service life of over 100,000 miles. The spark plug also incorporates a purified alumina powder insulator for strength and thermal conductivity, along with five ribs to prevent flashover. Machine-rolled threads prevent seizing or cross-threading during installation and removal. Key specifications include a 14mm thread diameter, 1.25mm thread pitch, and a projected 0.4mm iridium center electrode. The ground electrode is fine wire platinum, and the plug is designed with a resistor. Specific torque specifications are provided for both cast iron and aluminum cylinder heads. This spark plug is compatible with a wide range of vehicles from 2020-2023, including various Buick Enclave, Chevrolet Traverse, and Ford models such as the Bronco Sport, Mustang, and multiple Transit variants. Always verify specific fitment for your vehicle's year, make, model, and engine.
