Delphi Pencil Ignition Coil

The Delphi Pencil Ignition Coil (also called a coil-on-plug ignition coil or COP coil) converts the vehicle's low battery voltage into the high voltage needed to fire the spark plug. This helps the engine start reliably, idle smoothly and burn fuel efficiently.

Key Features:

• Slim pencil-style design fits directly over the spark plug in coil-on-plug ignition systems
• Delivers a strong, consistent spark to support complete combustion
• Helps prevent misfires, rough idle, hesitation and poor fuel economy caused by a worn coil
• Built with insulated, heat-resistant construction for durability under engine heat and vibration
• Made by Delphi, a long-established OE supplier of ignition and engine management components

Replacing a weak or failing ignition coil restores smooth engine performance and helps protect the catalytic converter from unburned fuel. Installation is typically simple: unplug the electrical connector, remove the old coil and press the new coil onto the spark plug. Choose the correct part number for your engine from the available options.
