DENSO First Time Fit Ignition Coil Boot

The DENSO First Time Fit Ignition Coil Boot line gives you replacement coil boots for direct ignition and coil-on-plug systems. The boot sits between the ignition coil and the spark plug. It carries high-voltage spark energy to the plug and seals the plug well against moisture, oil and debris.

Key Features:

• Made by DENSO, a leading original equipment supplier of ignition and engine management components
• First Time Fit design aims for a proper fit and function on the application it is intended for
• Insulating rubber construction helps keep spark energy from escaping and helps prevent misfires
• Seals the spark plug well against contamination
• Suited to restoring ignition performance when a boot has cracked, hardened or worn out

Replacing worn coil boots helps restore smooth starts, steady idle and consistent combustion. It is often done together with spark plug service. Check the part number of the variant you choose to confirm the contents of that listing.
