Chevrolet HEI Cross-Fire Coil, Cap & Rotor Kit by Davis Unified Ignition®

Matched coil, cap and rotor combine high-output ignition with brass-terminal connections.

This Davis Unified Ignition® Cross-Fire Street/Strip kit combines a high-output HEI coil with a distributor cap and rotor. The 50,000-volt coil is designed for operation through 7,000 rpm, while brass cap terminals improve conductivity and resist corrosion. The Cross-Fire cap organizes the Chevrolet plug leads by cylinder bank to reduce wires crossing over the engine. The kit includes nylon rotor screws. Plug gaps up to 0.055 inch may be used where suitable for the engine and ignition combination.
