NGK Nissan 240SX 1990-1989 Spark Plug Wire Set

This NGK spark plug wire set is what you get when you need to replace the wires on your 1989 or 1990 Nissan 240SX. These wires are built to handle the high voltage needed to fire your spark plugs, ensuring your engine runs smoothly. They are designed to meet or exceed the original equipment specifications for your car, meaning they fit right and perform as expected.

NGK uses a variable pitch resistor in these cables, which helps control resistance for outstanding electrical conductivity. The outer jacket is made from EPDM and silicone, materials known for their strength and ability to contain high voltage without breaking down. Inside, the insulation also helps keep that high voltage where it needs to be. This construction is key to preventing electrical interference, so your radio stays clear and your engine's computer gets clean signals. The spark plug and distributor boots are specifically made to fit your 240SX, with silicone sealer used to create a watertight connection at the spark plug end. Stainless steel terminals with multiple crimps bite into the wire for a strong connection that won't pull out, and a locking spring clip ensures a secure connection to the spark plug itself.
