DENSO Ignition Coil Boot

The DENSO Direct Ignition Coil Boot is a replacement spark plug boot for coil-on-plug (direct ignition) systems. It connects the ignition coil to the spark plug. It also helps seal the plug well against moisture, dirt and oil. If you're replacing a worn, cracked or carbon-tracked coil boot, this part helps restore a reliable connection.

Key Features:

• Replacement boot for direct ignition coil-on-plug applications
• Helps deliver spark energy from the coil to the spark plug
• Flexible insulating construction resists heat, vibration and engine bay conditions
• Helps protect the spark plug connection from moisture and contaminants
• Made by DENSO, an OE supplier of ignition and engine management components

Replacing a damaged boot can help prevent misfires, rough idle and hard starting. It is often done with a spark plug or ignition coil service. Choose the specific variant for your application from the options on this page.
