Prestolite ProConnect Spark Plug Wire Set GM

The Prestolite ProConnect Spark Plug Wire Set (also called an ignition wire set or spark plug cable set) is a replacement ignition component for GM cars and trucks. It carries high-voltage current from the ignition coil or distributor to each spark plug. This supports a smooth idle, reliable starts and consistent engine performance.

Key Features:

• Professional, O.E.-grade design intended to match original equipment form, fit and function
• Preassembled wire sets with molded boots and terminals for a secure connection at the plugs and the coil or distributor
• Insulated construction made to hold up to underhood heat and electrical demands
• Available in several wire styles and colors across the ProConnect line, so you can match the original ignition setup
• Backed by a limited lifetime warranty

Worn, cracked or failing spark plug wires can cause misfires, rough running, reduced fuel economy and hard starting. Replacing them restores dependable spark delivery. Check each child item for the exact fitment and specifications of your application.
