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. 4 Wires (Coil Lead N/R)

LIMITED LIFETIME WARRANTY: See package for details

The NGK Part Number 8931 spark plug wire set is designed specifically for Subaru Legacy models from 1997 to 1999, offering reliable performance and superior electrical conductivity. These wires feature a high-quality variable pitch resistor cable construction that ensures consistent resistance across all channels, helping to maintain optimal engine performance. The outer jacket is made from durable EPDM/silicone materials, providing excellent protection against high voltage currents and environmental factors, while the inner insulation offers outstanding dielectric strength to prevent electrical leaks.
NGK’s magnetic core technology in these cables helps produce the necessary impedance to effectively suppress electromagnetic interference (EMI) and radio frequency interference (RFI) throughout the entire frequency spectrum. This results in minimized noise and interference, which can improve overall engine efficiency and communication between electronic components. The spark plug boots are engineered with OE or better specifications to guarantee a perfect fit, high performance, and long-lasting durability in demanding automotive environments. These boots are securely glued to the cables with a silicone sealer, ensuring a watertight seal that prevents moisture ingress and corrosion.
The stainless steel terminals utilize up to three serrated crimps, biting into the cable jacket and inner insulation for maximum terminal retention strength. This design ensures a secure connection that resists vibration and mechanical stress. Additionally, the locking C-shaped spring clip with corrosion-resistant plating provides a positive, secure connection to the spark plug, maintaining consistent electrical contact over time. These wires are backed by a limited lifetime warranty, demonstrating NGK’s confidence in their durability and quality.
Ideal for automotive enthusiasts and professional mechanics alike, this NGK spark plug wire set is a crucial component for maintaining reliable engine operation and optimal ignition performance in Subaru Legacy vehicles from the late 1990s. Its combination of advanced materials, precise engineering, and robust construction makes it a dependable choice for ensuring your vehicle’s ignition system functions smoothly and efficiently.
