["NGK Coil on Plug Boot", "No Wires Req'd", "4 Required"]
The direct ignition coil boot insulates the high-voltage connection between the ignition coil and the spark plug in coil-on-plug systems, preventing arcing and ensuring full spark energy reaches the plug. Signs of failure include: a misfire or rough idle, a check engine light with a misfire code for a specific cylinder, or visible carbon tracking and arcing damage on the boot. Replace damaged coil boots to restore full ignition performance.
