Moroso Mag-Tune High Performance Plug Wire Set

Big Block Chevy, 90° Boots, HEI, Under Header, Hi-Temp Sleeved Wire

Finally! Race wire sets that out perform the competition at a price that the budget minded racer can afford! New Moroso "Mag-Tune" wire sets are a premium, top of the line ignition wire.

These wires are custom fit for big block Chevy engines, designed to go under the exhuast. For HEI (post style) distributor caps. 90 degree boots assembled on both ends. Set also includes a 35" coil wire. The distributor end on the coil wire is unassembled, both a male and female end plus heat shrink tube are included so you can use a coil with either type - socket or post connection. Made in the USA.

This plug wire set starts off as their regular Mag-Tune 8mm wire and then an outer sleeve is added to protect against heat, abrasion, and the elements. They also have heat shrink tubing at each boot end and each wire is individually numbered to simplify installation.

These 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.
