High-voltage cable transmitting electrical energy from ignition coil to spark plugs in combustion engines.
An ignition cable, also known as a spark plug wire or high-tension lead, is a specialized electrical conductor designed to carry high-voltage pulses from the ignition coil or distributor to the spark plugs in internal combustion engines. It consists of a conductive core (typically carbon-impregnated fiberglass, copper, or stainless steel strands) surrounded by multiple layers of insulation (silicone rubber, EPDM, or other high-temperature polymers) and protective sheathing to prevent electrical leakage, electromagnetic interference, and environmental damage. The cable must maintain precise electrical resistance (typically 1,000-50,000 ohms per meter) to ensure proper spark timing and energy delivery while suppressing radio frequency interference (RFI).

Common failure causes include: insulation cracking from heat aging (especially above 150°C), carbon track formation from voltage leakage, terminal corrosion, physical damage from abrasion or rodent chewing, and increased resistance from moisture ingress or conductor degradation.
Use a digital multimeter set to ohms (Ω) scale. Measure resistance between the two terminals. Acceptable range is typically 1,000-50,000 ohms per meter of cable length. Also perform visual inspection for cracks, burns, or corrosion, and check for arcing in dark conditions.
No. Cables must match the engine's specific requirements: correct length, terminal type (boot style and connection), resistance specification (suppression vs. non-suppression), temperature rating, and diameter for proper routing and clearance.
