Ignition Coil and Iridium Spark Plugs for Ford F-150 (2011-2016) 5.0L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2011-2016 Ford F-150

Complete 8-Cylinder Ignition Overhaul: Restores factory secondary ignition voltage, idle stability, and combustion efficiency on the 5.0L Coyote V8 powertrain.

The Stock F-150 Dielectric Breakdown & Thermal Fatigue

Under continuous high thermal cycling and severe towing loads, OEM coil-on-plug boots and epoxy potting suffer internal dielectric breakdown. This results in secondary voltage leakage, micro-arcing, and intermittent misfires under load. Over time, stock plug electrodes suffer gap erosion, escalating secondary ignition resistance and straining the PCM coil drivers.

The Engineering Solution

This ignition kit pairs eight high-output coil assemblies featuring reinforced copper primary and secondary windings with eight fine-wire iridium spark plugs. High-grade silicone boots isolate high voltage to eliminate arcing, while durable blade terminals maintain low-resistance contact. The fine-wire iridium center electrodes lower required ignition voltage and maximize flame kernel propagation for reliable combustion under load.
