NGK Audi 80 1990-1988 Spark Plug Wire Set

If you're working on your 1985-1987 Audi 4000, these NGK spark plug wire sets are a solid option for getting your ignition system back in shape. They're built to match the original equipment specifications, meaning they'll fit right and perform like the factory wires did when your car was new. This is important because a good spark plug wire set ensures that the spark from your ignition coil makes it to the spark plug efficiently, which is key for smooth engine operation and good fuel economy.

NGK uses a tinned copper core wire, which is a detail often found on European vehicles like your Audi. This core is wrapped in a high-temperature silicone outer jacket and an EPDM/silicone inner insulation. This combination is designed to handle the high voltage needed to create a spark while also resisting heat and preventing voltage leaks. They also build in RFI suppression right into the connectors and boots to help keep radio interference down. The boots are sealed to the cable with silicone to keep moisture out, which is crucial for reliable starting and running, especially in damp conditions.
