NGK Universal Wire Sets use the same high quality carbon core cable of our direct fit sets and are available in the most common 4, 6 and 8 cylinder vintage engine configurations. NGK universal sets feature 'cut to fit' spark plug wire leads with straight plug boots, 90 degree distributor boots with stainless steel terminals and nipples, and include an installation kit with instructions to complete your installation. High-temp premium silicone outer jacket and inner EPDM/silicone insulation contain high voltage currents for excellent dielectric strength. Carbon suppression core delivers low resistance and great EMI/RFI noise suppression. Spark plug boots are glued to NGK cable with a silicone sealer for a watertight seal.
