The Moroso Ultra spark plug wire set for SBC over-valve-cover routing includes 90° plug boots and HEI compatibility in red, intended for small-block Chevy engines that route wires over the valve cover but need right-angle boots. The 90° ends assist clearance around plug wells and fit common over‑cover geometries while supporting HEI distributor connections where required by the ignition setup.
