Mr. Gasket Custom Wire Loom Kits eliminate crossfire and keep spark plug wires uniformly spaced and routed away from hot headers or exhaust manifolds. Manufactured from heat-resistant black plastic and a perfect fit for 7mm and 8mm plug wires, these universal kits include a pair of 4-hole wire separators, eight 2-hole wire dividers, and four chrome-plated steel brackets that can be attached to valve covers to clean up and customize any engine compartment.
