Overview

The Pulstar IDG1H is an Iridium PlasmaCore spark plug designed to improve horsepower, torque, and MPG while reducing emissions. Its Pulstar Pulse technology enhances fuel ignition for more efficient combustion, leading to increased cylinder pressure and power output. Constructed with a fine-wire iridium center electrode for durability and resistance to corrosion and arc erosion, this plug ensures a consistent and stable spark.

Show original supplier description

The Pulstar IDG1H Iridium PlasmaCore Plug is engineered to optimize engine performance by enhancing the combustion process. Its innovative Pulstar Pulse technology utilizes a patented capacitor to deliver a powerful, controlled spark, leading to more efficient fuel burning. This increased efficiency translates to higher horsepower, improved torque, and better fuel economy, all while helping to reduce emissions. The plug’s design focuses on maximizing the power stroke by increasing cylinder pressure, which results in more force being delivered to the crankshaft and ultimately, more power to the wheels. The construction features a fine-wire iridium center electrode, chosen for its exceptional hardness, density, and high melting point. This material choice makes it highly resistant to corrosion and arc erosion, ensuring longevity even in high-temperature engine environments. The plug's insulator boasts a sturdier profile and a more robust ceramic build, enhancing its tensile and dielectric strength for greater reliability. The ground electrode is made of nickel for durability. Key specifications include a 14mm thread diameter, 1.25mm thread pitch, and a gasket seat type. The reach is 26.5mm, with a 5/8" (16mm) hex size. The pre-set gap is .039" (1.0mm). It's important to note that the gap should not exceed 1.4mm, and for TC/SC vehicles, it should not exceed 0.64mm. This spark plug is designed for a longevity of up to 100,000 miles and comes with a 1-year warranty.
