Product Description

The Moroso 73753 is an Ultra 40 race spark plug wire set in black, built for GM Gen V LT1/LT4 applications - 2014-on Corvette, 2014-on truck & SUV, and 2016-2024 Camaro - running 5.3L or 6.2L engines. The Ultra 40 design uses a spiral-wound nickel/copper alloy conductor at 40 ohms per foot to deliver high spark energy while keeping electromagnetic and radio-frequency interference low - valuable on engines running modern ignition and electronics.

A Kevlar core gives the wire roughly four times the tensile strength of typical aramid-fiber cores, and the closely-woven, silicone-impregnated fiberglass jacket adds up to 8,000 volts of extra insulation while protecting against header heat, chafing, and contaminants. The 8.5mm black wires use multi-angle boots for flexible routing in tight engine bays, and come as a complete set ready to install.
