Keep high-voltage spark energy where it belongs with the ThunderCore PRO Coil Boot Kit 900-P2096-6 (also written 900P20966), an OE-replacement service kit for coil-on-plug (COP) and coil-near-plug (CNP) ignition systems. It drops in as a direct-fit replacement for the 2010-2014 FJ Cruiser, 2007-2011 and 2013 Lexus GS350, 2007-2011 and 2013-2016 Lexus GS450h, 2006-2015 Lexus IS250, 2006-2014 Lexus IS350, 2010-2013 Toyota 4Runner, 2010-2014 Toyota FJ Cruiser, and 2011-2013 Toyota Tundra — see the "Vehicles it fits" section for engine specifics and the full application list.
In COP and CNP setups, the coil boot is the insulative path between the ignition coil and the spark plug. Over time these boots can degrade from heat, vibration, or chemical exposure, which can lead to arc-through, misfires, or hard starting. If worn boots are the cause, this kit replaces them.
- OE Replacement Quality: engineered to match OE dielectric strength, boot length, and connector geometry.
- Restores Ignition Insulation: fresh boots help provide proper spark isolation and reduce voltage loss.
- Heat & Chemical Resistant: built from high-temp silicone and reinforced materials to resist oil, fuel, and under-hood heat.
- Complete Kit Coverage: includes boots, springs, and insulators for full-cylinder service.
Interchange: 156026

Frequently Asked Questions
What does a coil boot do?
In coil-on-plug and coil-near-plug systems, the coil boot is the insulative path between the ignition coil and spark plug, carrying high voltage while sealing out heat and moisture.
What vehicles does this kit fit?
It's a direct-fit replacement for the listed FJ Cruiser, Lexus GS350, GS450h, IS250, IS350, and Toyota 4Runner, FJ Cruiser, and Tundra applications. See the "Vehicles it fits" section for the full list and engine details.
What's included in the kit?
The Coil Boot Kit includes the boots, springs, and insulators needed for full-cylinder service, making it suited to ignition tune-ups or preventative maintenance.
What are signs my coil boots may need replacing?
Boots that degrade from heat, vibration, or chemical exposure can cause arc-through, misfires, or hard starting. Diagnose the cause first; if worn boots are to blame, this kit replaces them.
What interchange number does this kit replace?
This kit cross-references interchange number 156026. Confirm fitment for your specific vehicle before ordering.
