NGK Audi 90 Quattro 1992-1990 Spark Plug Wire Set

If you're working on your 1990 or 1991 Audi 90 Quattro, a fresh set of spark plug wires from NGK can make a real difference. These wires are built to match the original equipment specifications, ensuring they fit right and perform reliably. They carry the high voltage needed to fire your spark plugs, which is crucial for smooth engine operation and consistent power delivery.

NGK uses a premium 29-gauge tinned copper core wire, which is common on certain European models and helps maintain excellent dielectric strength. The outer jacket is made of high-temperature silicone, while the inner insulation uses a blend of EPDM and silicone. This construction helps contain the high voltage currents and resist damage from engine heat. NGK also builds in RFI suppression right at the spark plug and distributor connectors, which helps prevent radio interference. The spark plug boots are securely glued to the cable with silicone sealer, creating a watertight seal to keep moisture out.

This set is designed as a direct replacement, meaning it should install without any major modifications. Having good spark plug wires is key to getting the most out of your ignition system.
