Keep spark energy moving cleanly from the ignition coil to the spark plug with the ThunderCore PRO Coil Boot 900-P2122. It installs as a direct-fit replacement for the listed Honda CR-V applications — the 2002-2003 CR-V and the 2005-2014 CR-V.
A coil boot is the insulating sleeve that bridges the connection between the ignition coil and the spark plug. It channels the high-voltage current down to the plug while surrounding that path to help keep the spark contained. Over time boots can harden, crack, or develop carbon tracking, which can let voltage arc to ground and show up as a cylinder misfire.
Spark transfer: carries high-voltage energy from the ignition coil to the spark plug.
High-voltage insulation: encloses the coil-to-plug connection to help resist arcing to ground.
Direct-fit replacement: serves as a replacement boot for the listed Honda CR-V applications.
Signs it may need replacing: hardened, cracked, or carbon-tracked boots can cause a misfire — if a failed boot is the cause, this restores the insulated path.
Diagnose the source of any misfire before replacing, as other components can produce the same symptom.

Frequently Asked Questions
What does a coil boot do?
It is the insulating sleeve between the ignition coil and the spark plug, carrying high-voltage current to the plug while helping keep that spark contained and resisting arcing to ground.
Which vehicles does the 900-P2122 fit?
It is a direct-fit replacement for the listed Honda CR-V applications: the 2002-2003 CR-V and the 2005-2014 CR-V. Check the Buyer's Guide tab to confirm your vehicle.
What are signs a coil boot may need replacing?
Hardened, cracked, or carbon-tracked boots can let voltage arc to ground, which may show up as a cylinder misfire. Diagnose the cause before replacing, since other parts can cause misfires too.
What number does this part interchange with?
This coil boot cross-references to SPP154E. Its own manufacturer part number is 900-P2122.
Will replacing the boot fix my misfire?
If a failed boot is the cause of arcing, replacing it restores the insulated coil-to-plug path. Confirm the boot is the source first, as coils, plugs, or other components can also cause a misfire.
