Proflow spark plug terminals are sold for those who like to make their own set or repair a damaged lead

The Proflow 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. If you prefer you can still fold the core under the traditional way

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!

Features:

• Dual-crimp terminals
• Can be used as Straight terminal or slightly angled
• Work with 7mm, 8mm 8.5mm diameter leads, Any bigger you are required to buff down the outer insulator slightly
