IEF1H10 Fine Wire Iridium Spark Plug

► Product Description Experience a new level of performance and efficiency with Pulstar spark plugs, featuring patented Plasmacore technology that was developed in collaboration with a US Department of Energy laboratory. These spark plugs use an internal capacitor to store energy; when released, an ultra-high-intensity electrical pulse saturates the fuel with combustion-enhancing plasma, ensuring instantaneous ignition and the most rapid burn possible. By optimizing the combustion process in this way, Pulstar spark plugs deliver unparalleled increases in horsepower and torque, while enhancing fuel economy and reducing emissions. Engineered for durability and reliability, the automotive line employs a high-quality iridium material to resist corrosion and arc erosion and a fine-wire design to ensure a precise and powerful spark. With Pulstar's Plasmacore technology, you can unlock your engine's full potential and enjoy a smoother, stronger and more satisfying driving experience. ► Shell Thread 14mm Pitch 1.25mm Reach 25mm Hex Size 5/8" (16mm) Seat Taper Terminal Type Solid ► Center Electrode Material Iridium Type Fine Wire Size 0.6mm Projection Projected ► Other Resistor Yes Heat Range 1 Length to Seat 54.5
