Ignition Coil & Spark Plugs for Ford Flex Taurus (2016-2019) 3.5L V6

Direct-Replacement Ignition Coil & Spark Plug Kit for 2016-2019 Ford Taurus

What it Does: Replaces degraded factory ignition components with high-temperature coils and platinum plugs to restore proper voltage delivery and eliminate misfires under load.

The Stock Taurus Ignition Weakness

The OEM ignition system on the 3.5L Cyclone V6 is highly susceptible to thermal degradation over extended mileage intervals. Positioned tightly within the D3 chassis engine bay, the rear bank of coils suffers severe heat soak from the exhaust manifold and firewall. This relentless thermal cycling breaks down the internal epoxy potting of the factory coils, causing internal micro-arcing, weak voltage output, and eventual P0300-series misfire codes. Furthermore, standard factory spark plug electrodes wear down over time, widening the spark gap and forcing aging coils to operate at higher resistance. This cascading failure results in sluggish throttle response, reduced fuel economy, and rough idle quality.

The Engineering Solution

This complete ignition kit provides a robust mechanical fix for the Duratec 35's spark degradation issues. The replacement ignition coils feature high-conductivity copper windings sealed in an advanced thermal-resistant epoxy, engineered to withstand extreme rear-bank engine bay temperatures without internal breakdown. Precision female blade terminals ensure a secure, low-resistance connection to the factory wiring harness. Coupled with platinum premium-grade spark plugs, the system guarantees a potent, reliable spark event. The platinum center electrodes drastically reduce spark erosion compared to copper, maintaining exact gap specifications across tens of thousands of miles. This powerful synergy between resilient coils and durable platinum plugs restores factory efficiency, eliminates misfires, and optimizes combustion.
