These spark plug terminals are what you need when you custom make your own sets. Available in 100 quants.

• 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 Degree 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!
• Dual-crimp spark plug terminals
