Keep high-voltage spark flowing cleanly from coil to plug with the ThunderCore PRO Coil Boot Kit 900-P2052-6 (also written 900P20526), an OE-replacement kit for coil-on-plug (COP) and coil-near-plug (CNP) ignition systems. It drops in as a direct-fit replacement for the 2001-2004 Chevrolet Tracker, 1999-2005 Suzuki Grand Vitara, 2004 Suzuki Vitara, and 2002-2006 Suzuki XL-7 — see the Buyer's Guide tab for engine-level detail.

In COP and CNP setups, the coil boot forms the insulative path between the ignition coil and the spark plug. Heat, vibration, and chemical exposure can degrade the boots over time, leading to arc-through, misfires, or hard starting — signs the boots may need replacing. If worn boots are the cause, this kit replaces them.

  • OE Replacement Quality: Engineered to match OE dielectric strength, boot length, and connector geometry.
  • Complete Kit Coverage: Includes the boots, springs, and insulators needed for full-cylinder service — ideal for tune-ups and preventative maintenance.
  • Heat & Chemical Resistant: Constructed from high-temperature silicone and reinforced materials to resist oil, fuel, and under-hood heat.
  • Restores Ignition Insulation: Replaces worn or cracked boots to help maintain proper spark isolation and limit voltage loss.
