Restore spark insulation and secure coil-to-plug contact with the ThunderCore PRO Coil Boot Kit 900-P2084-4. This OE-replacement ignition service kit is a direct-fit solution for the 2007-2015 Honda Fit (see the "Vehicles it fits" section for engine coverage). In coil-on-plug (COP) and coil-near-plug (CNP) systems, coil boots form the insulative path between the ignition coil and the spark plug; over time they can degrade from heat, vibration, or chemical exposure, which can lead to arc-through, misfires, or hard starting. If worn or cracked boots are the cause, this kit replaces them.
Whether you're replacing a single boot or servicing the entire engine set, this kit is designed to match factory ignition coils and spark plugs for COP and CNP applications.
