NGK variable-pitch resistor spark plug wire sets provide uniform resistance and outstanding electrical conductivity. An EPDM/silicone outer jacket and inner insulation contain high-voltage current for excellent dielectric strength, while the variable-pitch magnetic core suppresses interference across the full frequency spectrum for strong EMI/RFI noise suppression. 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.
