The JBA PowerCables ignition wire set for 1996–2003 GM 4.3L trucks lowers spark resistance to free more ignition energy and help consistent firing. Wire-wound mag conductors reduce electromagnetic interference, while 100% silicone jackets and clearance-optimized boot ends resist heat and abrasion. Custom lengths with cylinder ID labels ease installation and thicker diameters improve under-hood appearance.
