NGK Toyota 4Runner 1991-1989 Spark Plug Wire Set

NGK is known for making reliable ignition components, and this spark plug wire set is no different. If you're working on your 1989-1991 Toyota 4Runner or Pickup, these wires are built to keep your engine running smoothly. They handle the high voltage needed to fire your spark plugs, ensuring a consistent spark for optimal combustion.

These wires use a variable pitch resistor core, which helps manage electrical resistance for outstanding conductivity. The outer jacket is made of EPDM and silicone, materials chosen for their ability to contain high voltage and resist damage. Inside, the insulation is designed for excellent dielectric strength, meaning it keeps the electricity where it needs to be. NGK also pays attention to the details, like using silicone sealer to create a watertight seal on the spark plug boots and stainless steel terminals with multiple crimps for a strong connection. The spring clip on the spark plug terminal is designed to lock securely, preventing it from coming loose.
