Ignition Coil and Iridium Spark Plugs for Ford Mustang (2015-2020) 2.3L

Direct-Replacement Ignition Coil & Iridium Spark Plug Kit for 2015-2020 Ford Mustang

Direct Combustion Refresh: Engineered to eliminate spark blowout, high-RPM misfires, and rough idle under high cylinder pressures in forced-induction 2.3L EcoBoost platforms.

The Stock EcoBoost Ignition Breakdown

Under sustained boost and severe engine-bay thermal cycling, factory ignition coil assemblies suffer dielectric breakdown and internal winding resistance degradation. In direct-injected, turbocharged engines, worn standard spark plugs rapidly erode at the gap, inducing spark blowout, ignition lag, unburned hydrocarbon accumulation, and loss of top-end power under boost.

The Engineering Solution

This complete ignition kit features four high-output coil-on-plug assemblies engineered with high-conductivity copper windings, reinforced thermoplastic housings, and OEM-spec blade terminals for consistent energy transfer. Matched with fine-wire iridium spark plugs designed for superior thermal dissipation and high-spark reliability, this package restores factory combustion efficiency and stabilizes idle performance.
