The Moroso insulated Ultra 40 spark plug wire sleeve is an 8.65mm red 25ft roll that provides extra bore for thicker wires and boots while protecting against abrasion. The longer roll lets you cut custom lengths to organize and shield multiple ignition leads, and the red color aids quick visual identification of wire runs. It’s a practical choice when slightly larger sleeve diameter is needed.
