NGK Part Number 8139 Toyota 4Runner 1988 Spark Plug Wire Set – High-Performance Ignition Cables

NGK variable pitch resistor cables provide uniform resistance and ensure outstanding electrical conductivity in high-quality cables. Outer EPDM/silicone jacket and inner insulation contain high voltage currents for excellent dielectric strength. NGK variable pitch magnetic core cables produce the necessary impedance to suppress interference throughout the entire frequency spectrum for exceptional EMI/RFI noise suppression. OE or better specified spark plug and distributor boots ensure the highest quality fit, performance and durability in every application. Spark plug boots are glued to NGK cable with a silicone sealer for a watertight seal. Stainless steel terminals utilizing up to 3 serrated crimps bite into cable jacket and inner insulation for the highest terminal retention strength (wherever possible). Locking C-shaped spring clip with corrosion-resistant plating ensures a secure and positive spark plug terminal connection. 6 Wires (w/Coil Lead)

• LIMITED LIFETIME WARRANTY: See package for details

The NGK Part Number 8139 spark plug wire set is designed specifically for the 1988 Toyota 4Runner, providing reliable and efficient ignition performance. These wires feature a variable pitch resistor design that offers uniform resistance and excellent electrical conductivity, ensuring consistent spark delivery across all cylinders. The high-quality outer EPDM and silicone jacket, combined with inner insulation, effectively contain high voltage currents, resulting in superior dielectric strength and durability even in demanding conditions.
NGK’s magnetic core technology produces the necessary impedance to suppress electromagnetic interference (EMI) and radio frequency interference (RFI), maintaining optimal engine performance by minimizing electrical noise that can affect sensitive electronic components. The set includes six wires with a coil lead, all engineered to meet or exceed OE specifications for fit, form, and function.
Each spark plug boot is glued to the cable with a silicone sealer, creating a watertight seal that prevents moisture ingress and prolongs the lifespan of the ignition system. The stainless steel terminals utilize up to three serrated crimps for maximum retention strength, ensuring secure connections that resist vibration and wear. Additionally, the locking C-shaped spring clip with corrosion-resistant plating guarantees a reliable, positive connection to the spark plug, maintaining optimal contact over time.
Backed by a limited lifetime warranty, this NGK spark plug wire set offers a premium solution for restoring or upgrading your vehicle's ignition system. Whether you're performing routine maintenance or a complete tune-up, these wires deliver consistent performance, durability, and noise suppression for your 1988 Toyota 4Runner, helping ensure smooth engine operation and reliable starts.
