Zündkabeln

Zündkabeln, also known as spark plug wires, are essential components of a gasoline internal combustion engine's ignition system. Their primary function is to transmit the high-voltage electrical pulse generated by the ignition coil to the spark plugs. This pulse is what ignites the air-fuel mixture in the engine's cylinders, initiating the combustion process that powers the vehicle.

A typical Zündkabel consists of a conductive core surrounded by an insulating layer, usually made of silicone or rubber, to prevent voltage leakage. The core can be made of various materials, including carbon-impregnated fiber, copper, or resistive wire, each offering different levels of resistance to electrical current. The resistance plays a crucial role in managing radio frequency interference (RFI) generated by the ignition system.

Over time, Zündkabeln can degrade due to exposure to heat, oil, and vibration within the engine bay. This degradation can lead to increased resistance, cracked insulation, or loose connections. Symptoms of failing Zündkabeln include misfires, rough idling, reduced engine power, poor fuel economy, and difficulty starting the engine. Regular inspection and replacement of these components are recommended as part of routine vehicle maintenance to ensure optimal engine performance and prevent potential damage to other ignition system parts.
