The MSD's 8.5mm spark plug terminals feature "Dual Crimp" terminals. As the name implies, the terminals feature two crimps; one for the sleeve of the wire and another separate crimp to grasp the conductor.
By having separate crimps, the conductor doesn't need to be bent 180° and get squeezed between the terminal and sleeve. This individual conductor crimp produces a more secure crimp and there is less chance of spark arcing to the engine block or exhaust manifold through the boot!
