The set includes nine 10.5mm cables with straight high-temperature boots designed for easy push-and-twist installation. They’re intended as a direct replacement to restore crisp ignition performance when existing wires have become brittle, high-resistance, or damaged.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these wires improve ignition performance?\u003c\/h3\u003e\n\u003cp\u003eThe spiral-core construction reduces electrical resistance and helps deliver a stronger, more consistent spark to each plug. Superior EMI\/RFI suppression prevents interference with onboard electronics and radios, while the heavy dielectric insulation preserves spark energy under high voltage.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eSpiral core for low-resistance spark delivery\u003c\/li\u003e\n  \u003cli\u003eHigh dielectric strength glass braid and silicone jacket\u003c\/li\u003e\n  \u003cli\u003eEMI\/RFI suppression to protect sensors and radios\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eAre these wires durable enough for high heat and abrasion?\u003c\/h3\u003e\n\u003cp\u003eNilight wires use heavy-duty silicone and a glass-braid insulation layer to resist heat, oil, and wear commonly found in engine bays.
