Keep high-voltage spark flowing cleanly from coil to plug with the ThunderCore PRO Coil Boot 900-P2075. This OE-replacement coil boot is a direct-fit replacement for a range of 2006-2012 applications, including the 2006-2007 Buick Rainier, 2007-2012 Chevrolet Colorado, 2006-2009 Chevrolet Trailblazer, 2006 Chevrolet Trailblazer EXT, 2007-2012 GMC Canyon, 2006-2009 GMC Envoy, 2006 GMC Envoy XL, 2007-2010 Hummer H3, 2009-2010 Hummer H3T, 2006-2008 Isuzu Ascender, 2008 Isuzu I-370, and 2006-2009 Saab 9-7X. See the Buyer's Guide tab for engine-level fitment.
In coil-on-plug (COP) and coil-near-plug (CNP) ignition systems, the coil boot forms the insulative path between the ignition coil and the spark plug. Heat, vibration, and chemical exposure can degrade a boot over time, leading to arc-through, misfires, or hard starting. If a cracked or worn boot is the cause, this replaces it to restore proper spark isolation.
