Ignition Coil and Iridium Spark Plugs for Ford Bronco (2021-2024) 2.7L

Direct-Replacement Ignition Coil and Iridium Spark Plug Kit for 2021-2024 Ford Bronco

What it Does: The ignition coil and iridium spark plug kit replaces worn factory ignition components on the 2021-2024 Ford Bronco to eliminate cylinder misfires, restore clean combustion under boost, and stabilize idle quality.

The Stock Ford Bronco Ignition Breakdown & Heat Fatigue

In twin-turbocharged engines like the twin-turbo 2.7L EcoBoost, cylinder pressures and under-hood thermal cycles are severe. Over time, the factory coil packs degrade from heat soak, developing micro-fractures in the epoxy casing that bleed secondary voltage to ground. Coupled with factory spark plugs whose electrodes erode under high cylinder pressures, this leads to spark blowout under heavy load, erratic idle, loss of mid-range torque, and diagnostic trouble codes such as P0300 through P0306.

The Engineering Solution

This direct-fit ignition overhaul kit restores full combustion efficiency. The six coil-on-plug pencil coils feature high-dielectric epoxy housing and premium copper windings to resist insulation breakdown under sustained thermal cycling. High-temp silicone boots prevent flashover down the plug well. Paired with six fine-wire iridium spark plugs, this kit provides a concentrated, stable arc that withstands peak manifold boost pressures without quenching, ensuring crisp throttle response and complete fuel burn.
