Keep every cylinder firing cleanly with the ThunderCore PRO Coil Boot Kit 900-P2038-4, an OE-replacement kit that drops in for the 2004-2006 Chevrolet Colorado, 2004-2006 GMC Canyon, 2006 Isuzu I-280, and 2007-2008 Isuzu I-290. See the Buyer's Guide tab to confirm your engine.

In coil-on-plug (COP) and coil-near-plug (CNP) systems, the coil boot forms the insulative path between the ignition coil and the spark plug. Over time these boots can degrade from heat, vibration, and chemical exposure, which can lead to arc-through, misfires, or hard starting. If worn or cracked boots are the cause, this kit replaces them to restore proper spark isolation and secure coil-to-plug contact.

  • OE Replacement Quality: matched to OE dielectric strength, boot length, and connector geometry.
  • Complete Kit Coverage: includes the boots, springs, and insulators needed for full-cylinder replacement, ideal for ignition tune-ups and repairs.
  • Heat & Chemical Resistant: built from high-temperature silicone and reinforced materials to resist oil, fuel, and under-hood heat.
  • Exact OE Fit: designed for factory coil-on-plug and coil-near-plug ignition systems.
