Restore high-voltage spark insulation between the ignition coil and spark plug with the ThunderCore PRO Coil Boot 900-P2126 (also written 900P2126). This OE-replacement boot drops into coil-on-plug (COP) and coil-near-plug (CNP) ignition systems on the 2000-2002 Chevrolet Prizm, 2000-2005 Toyota Celica, 2000-2008 Toyota Corolla, 2000-2006 Toyota MR2 Spyder, 2003-2008 Pontiac Vibe, and 2003-2008 Toyota Matrix — see the Buyer's Guide tab for engine-level fitment.
Over time, coil boots degrade from heat, vibration, and chemical exposure, which can lead to arc-through, misfires, or hard starting. Replacing a worn or cracked boot re-establishes proper spark isolation and a secure coil-to-plug connection.
What does this coil boot do?
It serves as the insulative path between the ignition coil and the spark plug in coil-on-plug (COP) or coil-near-plug (CNP) systems, maintaining high-voltage spark isolation and a secure coil-to-plug connection.
What vehicles does the 900-P2126 fit?
It's a direct-fit replacement for the 2000-2002 Chevrolet Prizm, 2000-2005 Toyota Celica, 2000-2008 Toyota Corolla, 2000-2006 Toyota MR2 Spyder, 2003-2008 Pontiac Vibe, and 2003-2008 Toyota Matrix. See the Buyer's Guide tab.
What are signs a coil boot may need replacing?
Boots can degrade from heat, vibration, or chemical exposure, which may lead to arc-through, misfires, or hard starting. Diagnose the cause before replacing, since these symptoms can have other sources.
What is the boot made from?
It's constructed from high-temp silicone and reinforced materials chosen to resist oil, fuel, and under-hood heat in the engine bay.
Is this an OE-replacement part?
Yes. It's engineered to match OE dielectric strength, boot length, and connector geometry for compatibility with the factory ignition coils and spark plugs on the listed applications.
