Finally! Replacement wire sets that out perform the competition at a price that can't be beat! New Moroso "Mag-Tune" wire sets are a premium, top of the line ignition wire. 7mm diameter. Direct fit for '93-'99 Dodge trucks with 5.2L and 5.9L V8 engines. Includes coil wire. These wires exceed OE specs. Made in USA. Mag-Tune Moroso wires are manufactured with a stainless nickel alloy wire which is wound 32 times per inch around a conductive laytex coated, heavy fiberglass core. This conductor meets O.E. radio frequency interference (RFI) requirements while operating at one-tenth the resistance of conventional "Carbon Core" conductor. All ignition wire jacket is made from two layer EPDM (ethlyene propylene diene monomer) for the best heat protection and highest dielectric strength. Layers are separated by a fiberglass reinforcing braid for added pull strength. The spark plug boots are all silicone and sure grip snap-lock terminals are used.
