ThunderCore PRO Coil Boot Kit P/N:900-P2072-8
Keep high-voltage spark where it belongs with the ThunderCore PRO Coil Boot Kit (P/N 900-P2072-10, also written 900P207210). This ThunderSpark kit is an OE-replacement service set that restores the insulative path between the ignition coil and spark plug on coil-on-plug (COP) and coil-near-plug (CNP) systems. It fits a range of Ford trucks and chassis: the 2008-2010 F-250 Super Duty, 2009-2010 F-350 Super Duty, 2009-2015 F-450 Super Duty, 2009-2015 F-550 Super Duty, and the F-53 Motorhome Chassis for 2009 and 2011-2014. See the Buyer's Guide tab for engine-specific details.
Over time, coil boots can degrade from heat, vibration, or chemical exposure, which may lead to arc-through, misfires, or hard starting. If worn or cracked boots are the cause, this kit replaces them to help restore proper spark isolation and secure coil-to-plug contact.
