NGK mag-core spark plug wire set for the Saab 9-2X / Subaru Impreza-Legacy-Outback-Forester 2.5. Stainless winding over a premium ferrite magnetic core keeps resistance ultra-low for a stronger spark while suppressing EMI/RFI interference, and a high-temp silicone jacket over EPDM/silicone insulation gives high dielectric strength. OE-or-better boots are silicone-sealed to the cable for a watertight seal, with stainless terminals, serrated crimps and a locking C-clip for a secure fit.
