    A cut-to-length set is the practical answer for a custom build, a relocated distributor or a swap where no off-the-shelf wire set routes correctly. This kit supplies the wire, boots and terminals to build a complete V8 set for either an HEI or a non-HEI style distributor cap, so one box covers both cap styles. Multi-angle boots let each finished wire be indexed for the cleanest path around headers, brackets and accessories.

    Moroso 73764 Installation Notes:

    • 8mm Ultra 40 spiral core wire measures only 40 ohms per foot, roughly one tenth the resistance of a carbon core wire.
    • Low resistance suits high output and multiple spark ignition boxes while the spiral wind still controls radio frequency interference.
    • Universal cut-to-length kit with terminals for both HEI and non-HEI style distributor caps.
    • Two layer EPDM jacket separated by a reinforcing braid handles underhood heat and adds pull strength.
    • Silicone boots with snap lock terminals hold a positive connection at the plug and the cap.
    • Multi-angle boots let the plug end be rotated for the cleanest routing in a crowded engine bay.
    • Red wire, eight cylinder set, manufactured in the USA.

    Note: test-fit each routing before cutting, and use a proper ignition crimp tool so the terminal grips the conductor without severing the core.
