NGK Mercedes-Benz 250 1970-1968 Spark Plug Wire Set

If you're working on your 1968-1970 Mercedes-Benz 250 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 a proper fit and reliable performance for your classic German sedan. Getting the right spark plug wires is key to making sure each cylinder is firing correctly, which means your engine runs smoothly and efficiently.

NGK uses a tinned copper core wire, which is what certain European models, like your 250, originally came with. This core is then wrapped in a high-temperature silicone outer jacket and EPDM/silicone inner insulation. This combination helps contain the high voltage currents, giving you strong dielectric strength to prevent misfires. They also build in RFI suppression right into the connectors and resistor boots, which helps keep radio interference down. The boots are sealed to the cable with silicone for a watertight connection, so you don't have to worry about moisture getting in and causing problems.

This set is designed for a direct fit, meaning installation should be straightforward without needing any modifications. NGK backs these wires with a limited lifetime warranty, giving you peace of mind with your purchase.
