They combine a spiral core conductor for reduced electrical resistance and EMI suppression with heavy glass-braid insulation and thick silicone jackets to resist heat, oil, and abrasion around the engine bay. The kit includes nine wires sized to match common distributor- or coil-style ignition layouts and is intended as a direct replacement to restore connection integrity and consistent spark delivery.\u003c\/p\u003e\n\n\u003ch3\u003eHow will these wires affect engine starting and idle?\u003c\/h3\u003e\n\u003cp\u003eHigher conductivity and stable insulation help maintain a reliable spark at each plug, which can reduce misfires and make starts crisper.
