Located in the ignition system, the ignition coil creates the voltage needed for an electric spark in the spark plugs to ignite the fuel.
The Problem: When the ignition coil gaskets on certain GM light trucks dry rot—which they have a tendency to do—moisture can enter the coil boot, shortening the life span of each affected coil.
Our Response: To help you fix the problem and prevent future failure, NAPA Echlin’s Ignition Coil Maintenance Kit comes with direct-fit gaskets that reduce water intrusion in the boot and increase coil life. With applications for select GM trucks, NAPA Echlin’s kit covers more than 1.5 million VIO.
