Edelbrock Wire Separator Kit #22799 will organize spark plug wires on 4-, 6- and 8-cylinder engines and includes six separators (two 2-wire, two 3-wire and two 4-wire) designed to work with wire diameters up to 8.5mm. Edelbrock Separators are constructed of glass-fiber-reinforced nylon for durability that resists temperature up to 464 degrees. Each Separator features a click-lock folding design that securely hold wires in place to prevent cross-firing between cylinders. Separators have a textured black finish to blend in with any engine compartment and the Edelbrock logo lets everyone know that you've chosen the best.
