The NGK spark plug wire set for Mercedes-Benz 450SEL (1977–1979) provides OE-style replacement wiring engineered for fit and durability. Tinned copper core conductors are protected by a high-temp silicone outer jacket with EPDM/silicone inner insulation to maintain dielectric strength. RFI suppression is integrated into NGK's OE connector design and metallic resistor boots; spark plug boots are glued with silicone for a watertight seal. Includes 8 wires with coil lead and limited lifetime warranty.
