NGK Jaguar XJ12 1991-1989 Spark Plug Wire Set

If you're working on your 1989-1991 Jaguar XJS and need to replace the spark plug wires, this set from NGK is a solid option. These wires are built to handle the high voltage needed for a strong spark, which is crucial for smooth engine operation and efficient combustion. They're designed to be a direct replacement for your original wires, making the installation process straightforward.

NGK uses a magnetic core with stainless steel winding to create ultra-low resistance, helping to ensure a powerful spark reaches your plugs. The outer jacket is made of high-temperature silicone, and the inner insulation uses EPDM and silicone to maintain dielectric strength, keeping that high voltage contained. The boots are made to OE specifications, so they fit securely onto the spark plugs and distributor, and they're sealed with silicone to keep moisture out. The terminals use multiple crimps for a strong connection to the wire and a locking clip to ensure they stay connected to the spark plug.
