Without the timed ignition systems in our internal combustion engines, there would be no way to generate enough power for efficient operation. The fact that your Mercedes-Benz 420SEL has mechanically or electronically timed ignition means that it needs spark plug wires. The voltage necessary to detonate the air/fuel mixture effectively is transferred from your distributor or ECU in a specific order to the spark plug via your Mercedes-Benz 420SEL spark plug wires. Sometimes called high tension leads, these usually have a carbon fiber core wrapped in a fiberglass barrier, and covered with EPDM rubber for insulation from the heat in your engine.
