NGK mag-core spark plug wire sets deliver ultra-low resistance, a more powerful spark and excellent EMI/RFI noise suppression. A high-temp premium silicone outer jacket with EPDM/silicone inner insulation provides high dielectric strength, while stainless-steel winding over a premium ferrite magnetic core keeps resistance low. OE-or-better boots are glued to the cable with silicone sealer for a watertight seal, and stainless terminals with up to three serrated crimps plus a locking C-clip ensure secure, durable connections. Fits the GM Gen-III/IV Vortec V8 (GMT800).
