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 8691 spark plug wire set is engineered to deliver reliable performance and optimal electrical conductivity for Subaru Impreza models from 2001 to 2004 and Baja models from 2003 to 2006. These wires feature a high-quality variable pitch resistor design that provides uniform resistance, ensuring consistent spark delivery across all cylinders. The outer EPDM and silicone jackets, combined with inner insulation, contain high voltage currents effectively, offering excellent dielectric strength and durability in harsh engine environments.
The magnetic core within each wire creates the necessary impedance to suppress electromagnetic interference (EMI) and radio frequency interference (RFI), resulting in reduced engine noise and improved overall electrical system performance. Each wire is fitted with OE or better specified spark plug and distributor boots, which are glued with a silicone sealer to create a watertight seal, preventing moisture ingress and enhancing longevity.
Stainless steel terminals with serrated crimps secure the wires firmly to the cable jacket and inner insulation, providing maximum terminal retention strength while resisting corrosion. The locking C-shaped spring clips, plated for corrosion resistance, ensure a secure and positive connection to the spark plugs, minimizing misfires and ensuring consistent engine operation. This set includes four wires designed specifically for compatible Subaru models, offering a straightforward upgrade to improve ignition performance and reliability.
Backed by a limited lifetime warranty, the NGK spark plug wire set is built to meet or exceed OE specifications, delivering high-quality fit, performance, and durability in demanding automotive conditions. Proper ignition system function is critical for engine efficiency, starting, and emissions control, making this wire set an essential component for maintaining vehicle performance and longevity.
