Auto Extra Prostart Spark Plug Wire Set

The Auto Extra Prostart Spark Plug Wire Set (also called an ignition wire set or plug wire set) carries high-voltage current from the ignition coil or distributor to the spark plugs. This helps the engine start reliably and run smoothly.

Key Features:

• Custom-fit spark plug wire set made for specific engine applications
• Replaces worn, cracked or damaged ignition wires
• Boots and terminal ends are designed to seat securely on the spark plugs and the coil or distributor
• Helps restore a consistent spark and smooth engine performance

Worn plug wires can cause misfires, rough idle, hard starting and poor fuel economy. Replacing them is a routine tune-up item. Choose the part number that matches your engine from the variants listed on this page.
