The MSD 34615 Dual Crimp terminal is suitable for 8.5mm spark plug wire. This type of terminal features two crimps; one for the sleeve of the wire and another separate crimp to grasp the conductor. The separate crimps means that the conductor doesn't need to be bent 180° and get squeezed between the terminal and the sleeve. The individual conductor crimp produces secure crimp and there is less chance of spark arcing to the engine block or exhaust manifold. Sold individually (if you require a pack of 100pcs please call or email).
