Product Details
If you're working on your 1986-1991 Mercedes-Benz 420SEL and need to replace the spark plug wires, this set from NGK is a solid option. These wires are built to match the original equipment specifications, ensuring they fit right and perform as expected for your V8 engine.
NGK uses a tinned copper core wire, which is a specific requirement for certain European models like yours. This core, combined with a high-temperature silicone outer jacket and EPDM/silicone inner insulation, helps contain the high voltage needed for a strong spark. They also incorporate RFI suppression right at the spark plug and distributor connectors, which helps prevent radio frequency interference that could affect your car's electronics. The spark plug boots are sealed to the cable with silicone, creating a watertight connection to keep moisture out.
This set is designed for a direct fit on your 420SEL, as well as the 560SEC and 560SEL from the same years. NGK backs these wires with a limited lifetime warranty, giving you peace of mind.
