Ignition Coil and Iridium Spark Plugs for Ford Mustang (2011-2015) 3.7L

High-Output Ignition Coil and Iridium Spark Plug Kit for 2011-2015 Ford Mustang

Direct-fit ignition overhaul package: Replaces degraded factory coil packs and worn spark plugs to restore high-RPM spark energy, eliminate misfires, and stabilize idle across all six cylinders.

The Stock Mustang Ignition Breakdown

Under repeated thermal cycling and prolonged high-RPM operation, factory Ford 3.7L ignition coils suffer dielectric breakdown within the primary and secondary copper windings. The original boot seals harden over time, causing intermittent high-voltage arc-through and carbon tracking. Paired with eroded factory electrode gaps, this degradation causes cylinder misfires (DTC P0300-P0306), erratic idle, unburned fuel blow-by, and delayed throttle response under heavy load.

The Engineering Solution

This complete ignition kit features heavy-duty coil-on-plug assemblies engineered with high-conductivity internal copper windings and corrosion-resistant blade terminals for maximum energy transfer without thermal breakdown. Matched with fine-wire iridium spark plugs, the system provides a high melting point, superior quenching resistance, and a concentrated spark kernel. The result is rapid flame propagation, efficient combustion chamber burn, and rock-solid spark delivery up to the factory rev limit.
