ThunderCore PRO Coil Boot Kit P/N:900-P2109-4

$30.99

Description

Restore reliable spark insulation and secure coil-to-plug contact with the ThunderCore PRO ThunderSpark Coil Boot Kit 900-P2109-4. It drops in as an OE-replacement service kit for the 2009-2011 Suzuki Grand Vitara and 2010-2012 Suzuki Kizashi — see the Buyer's Guide tab for the full engine list. In coil-on-plug (COP) or coil-near-plug (CNP) systems, the coil boot is the insulative path between the ignition coil and the spark plug, and over time heat, vibration, or chemical exposure can degrade it, leading to arc-through, misfires, or hard starting. If worn or cracked boots are the cause of those symptoms, this kit replaces them.

OE-Replacement Quality: Engineered to match OE dielectric strength, boot length, and connector geometry.
Heat & Chemical Resistant: Constructed from high-temp 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 secure high-voltage contact.
Complete Kit Coverage: Includes the boots, springs, and insulators needed for full-cylinder replacement — ideal for ignition tune-ups and preventative maintenance.
