NGK Nissan D21 1989-1986 Spark Plug Wire Set

If you're working on your 1986-1989 Nissan D21 and need to replace the spark plug wires, this set from NGK is a solid option. These wires are built to ensure your engine gets a consistent spark, which is key for smooth running and efficient combustion. They help maintain the right electrical resistance, so the voltage gets to the spark plugs without getting lost along the way.

NGK uses a strong outer jacket made of EPDM and silicone to keep the high voltage contained, while the inner insulation adds to that dielectric strength. The magnetic core in these cables is designed to cut down on electrical interference, meaning you won't have radio static or other electronic noise issues. The boots are made to fit just right on your D21's spark plugs and distributor, and they're sealed with silicone to keep moisture out. The stainless steel terminals have multiple crimps to make sure they stay firmly attached to the wires, and the spring clip on the spark plug boot locks on securely for a good connection.
