If the late 1990’s GM used a funky looking cap and rotor, commonly referred to as the Vortech Distributor. These caps offer a corrected position of the terminals to ease the routing of the wires. MSD now offers a heavy duty version of this cap and rotor. The new pieces are molded from a more durable material for improved spark isolation. Brass terminals top it off.
