Ignition Coil + Spark Plugs for Ford F-250 F-450 F-550 (2020-2022) 7.3L

Direct-Replacement Ignition Coil and Spark Plug Kit for 2020-2022 Ford F-250, F-450, F-550 (P558)

What it Does: The complete ignition kit restores high-energy spark delivery and stabilizes combustion across all eight cylinders on 2020-2022 Ford Super Duty trucks operating under heavy payloads and towing cycles.

The Stock Ford F-250, F-450, F-550 Ignition Breakdown

Under continuous commercial hauling and heavy engine loads, the **7.3L Godzilla** OHV V8 generates elevated thermal loads inside the engine bay. Over extended service intervals, the stock coil pack epoxy and internal windings suffer from thermal fatigue, leading to dielectric breakdown, secondary voltage leakage, and internal shorting. Concurrently, factory spark plug electrodes erode, expanding the gap and increasing the required breakdown voltage. This degradation results in high-load spark blowout, hesitation under throttle tip-in, rough idling, and catalytic converter-damaging misfire events.

The Engineering Solution

This service kit replaces fatigued ignition components with direct-fit coils and matched platinum spark plugs engineered to withstand severe duty cycles. Built to supersede OEM **UF893**, each ignition coil uses high-grade copper primary and secondary windings encased in void-free dielectric potting resin to maintain rapid saturation and high secondary output voltage. The fine-wire platinum spark plugs provide superior resistance to spark erosion, reducing flame kernel quenching and maintaining optimal arc stability across the factory power band without thermal degradation.
