These sets are made using top quality 8.2 mm Taylor suppression core wire. This set is aimed specifically at Vertex OAC (internal coil) magnetos that need no terminals or boots for the mag end. These wires are slightly larger and don't fit into a stock Vertex cap. You will need to take care to open the cap to accept the bigger wires. If you run electronics on-board (tach, shift-light, data logger, etc.), these are the wires you want for your magneto. With only 40 ohms of impedance per foot, these wires curb RFI while ensuring long cap and rotor life. These wires don't endanger your internal coil like high impedance STREET suppression wires will. These wires all run LONG compared to standard Taylor, Mallory or MSD sets. You won't come up short! The 90 degree plug terminals and boots are installed for you. Trim to fit and install the wires into a CNC machined Vertex cap. Snug the brass lugs in the cap into the wires and you're ready!
