NGK Mercedes-Benz 450SEL 1979-1977 Spark Plug Wire Set

This NGK spark plug wire set includes all the necessary wires to replace the set on your 1977-1979 Mercedes-Benz 450SEL. These wires are built to match the original equipment specifications, ensuring a proper fit and reliable performance for your vehicle's ignition system. They play a crucial role in delivering the spark needed to ignite the fuel-air mixture in your engine's cylinders.

NGK uses a premium 29-gauge galvanized, tinned copper core wire, which is specifically required for certain European models like yours. This core material helps carry the high voltage current efficiently. The outer jacket is made of high-temperature silicone, while the inner insulation uses EPDM and silicone, providing excellent dielectric strength to contain the voltage. To prevent radio frequency interference (RFI), NGK builds suppression right into the spark plug and distributor connectors, featuring metallic resistor boots. The spark plug boots are securely attached to the NGK cable with silicone sealer, creating a watertight seal to keep moisture out.

This set is designed for a direct fit, meaning it should install without major modifications. NGK backs these wire sets with a limited lifetime warranty, offering peace of mind with your purchase.
