NGK BMW 635CSi 1989-1988 Spark Plug Wire Set

NGK is well-known for making reliable ignition components, and this spark plug wire set is built to match that reputation for your 1988-1989 BMW 635CSi. These wires are designed to provide excellent OE fit, meaning they'll install correctly and perform as the original equipment did, ensuring your engine runs smoothly. They are constructed for good durability, so you can expect them to last.

The construction features a high-temperature premium silicone outer jacket, which helps protect the wires from engine heat. Inside, the EPDM/silicone insulation works to contain high voltage currents, offering strong dielectric strength. For certain European models like yours, NGK uses a premium 29-gauge galvanized, tinned core wire. Radio Frequency Interference (RFI) suppression is built right into the spark plug and distributor connectors, helping to prevent interference with your car's electronics. The spark plug boots are sealed to the NGK cable with silicone sealer, creating a watertight connection to keep moisture out.
