ThunderCore PRO Coil Boot P/N:900-P2151

Description

Restore reliable high-voltage insulation between the ignition coil and spark plug with the ThunderCore PRO Coil Boot 900-P2151, an OE Replacement boot that drops in on the 2014-2015 and 2017-2018 Mazda 3, the 2012 Mazda 3 Sport, and the 2014-2018 Mazda 3 Sport. In coil-on-plug (COP) and coil-near-plug (CNP) systems, the coil boot is the insulative path between the ignition coil and the spark plug, and this one is engineered to match OE dielectric strength, length, and terminal fitment for secure coil-to-plug contact.

Exact OE Fit: designed for compatibility with factory ignition coils and spark plugs in COP and CNP setups.
OE Replacement Quality: engineered to match OE dielectric strength, boot length, and connector geometry.
Restores Ignition Insulation: replaces worn or cracked boots to help maintain proper spark isolation and prevent voltage loss.
Heat & Chemical Resistant: constructed from high-temp silicone and reinforced materials to resist oil, fuel, and under-hood heat.

Over time, boots degrade from heat, vibration, or chemical exposure. Signs a boot may need replacing include arc-through, misfires, or hard starting; if a failed boot is the cause, this restores the insulative path. See the Buyer's Guide tab for engine-level fitment.
