NGK Subaru Impreza 1998-1997 Spark Plug Wire Set

If you're working on your 1997 or 1998 Subaru Impreza or Legacy, a fresh set of spark plug wires from NGK can make a noticeable difference. These wires are built to handle the high voltage needed to fire your spark plugs, ensuring your engine runs smoothly. They're designed to replace your original wires, helping to restore lost performance and improve fuel efficiency if your old wires have started to degrade.

NGK uses a variable pitch resistor core in these cables, which helps manage resistance for consistent electrical conductivity. The outer jacket is made from EPDM and silicone, materials chosen for their ability to contain high voltage and resist damage. Inside, the insulation is also designed for strength. This construction helps suppress electromagnetic interference (EMI) and radio frequency interference (RFI), which can affect your car's electronics. The spark plug and distributor boots are made to fit precisely, just like the original parts, and are sealed with silicone to keep moisture out. For a strong connection, the stainless steel terminals use multiple crimps to grip the wire securely, and the spark plug clips are designed to lock on tightly.
