NGK Mercedes-Benz 560SL 1989-1986 Spark Plug Wire Set

When you're working on your 1986-1989 Mercedes-Benz 560SL and need to replace the spark plug wires, NGK offers a well-built set designed to get your engine running smoothly again. These wires are crucial for delivering the spark from your distributor to the spark plugs, ensuring proper combustion and engine performance. If your old wires are cracked, brittle, or showing signs of wear, replacing them with a quality set like this can help restore lost power and improve fuel efficiency.

NGK uses a premium 29-gauge galvanized, tinned copper core wire, which is what's required for certain European models like yours. This core is wrapped in a high-temperature silicone outer jacket and EPDM/silicone inner insulation. This combination is built to handle high voltage currents and maintain excellent dielectric strength, meaning the electricity stays where it needs to go. The spark plug boots are securely glued to the NGK cable with a silicone sealer, creating a watertight seal to keep moisture out. NGK also builds in RFI suppression right at the spark plug and distributor connectors, which helps prevent radio frequency interference.

This set is designed for an OE fit, meaning it should install without any major modifications. It's a solid option for getting your 560SL back to its proper running condition.
