MSD's 8.5mm spark plug terminals use a dual-crimp design, with one crimp for the wire's sleeve and a separate crimp for the conductor. Because the conductor doesn't need to be bent 180° and squeezed between the terminal and sleeve, the crimp is more secure and there's less chance of spark arcing to the engine block or exhaust manifold through the boot.
