DENSO Coil

DENSO ignition coil boots, also called coil-on-plug (COP) boots, are replacement components for direct ignition systems. Each boot connects an ignition coil to its spark plug and helps carry the high-voltage spark to the plug. Offered as boots or boot kits depending on the part number, they help restore reliable ignition performance when the original rubber has aged.

Key Features:

• Flexible rubber construction that seals the spark plug well against dirt and moisture
• Insulation that helps keep high-voltage energy from leaking or misfiring
• Designed as a replacement for worn, cracked or brittle coil-on-plug boots
• Made by DENSO, a leading original equipment supplier of ignition and engine management components

Replacing worn boots can help prevent misfires, rough idle and poor fuel economy caused by spark leakage. Choose the specific part number that matches your application from the variants listed on this page.
