ACCEL 7mm SuperStock Copper Universal Wire Sets are a true performance upgrade for tired old OE wires. A universal fit for pre-HEI ignitions, their graphite RFI suppression or copper cores make them perfect for street-driven applications. Classic ACCEL yellow with female/socket-style distributor boots and straight red plug boots, these wires have 450-degree-rated silicone jackets extruded over a tightly woven fiberglass braid that's applied over high-dielectric-strength EPDM inner insulation for performance that exceeds SAE specifications. They're also available with 90-degree boots and in blue with matching blue straight or 90-degree boots.
