6 High Performance Ignition Coil for Ford Taurus (2013-2016) 3.5L Engine

High-Response Ignition Coil Set for 2013-2016 Ford Taurus (Duratec 35/D3)

What it Does: Replaces the factory UF646 ignition coils with high-output units designed to provide consistent spark energy and eliminate misfires under heavy load or high thermal stress.

The Stock Taurus Ignition Weakness

The 3.5L Cyclone V6 engine in the Ford D3 chassis often suffers from ignition degradation caused by excessive heat soak within the engine valley. The OEM coil packs utilize standard-grade internal copper windings that, over time, develop micro-fractures due to thermal expansion and contraction cycles. This leads to increased internal resistance, causing the PCM to detect intermittent misfires (P0300-P0306), especially during wide-open throttle transitions. Furthermore, the factory epoxy potting is prone to becoming brittle, which allows moisture to penetrate the secondary windings, resulting in voltage leaks and a noticeable decrease in fuel efficiency and idle smoothness.

The Engineering Solution

These high-performance replacement coils are engineered with high-dielectric epoxy and reinforced thermal plastic housings to better insulate the internal components against the high-heat environment of the Duratec 35 engine bay. The internal architecture features an optimized primary and secondary winding ratio to ensure faster saturation times and a more intense spark discharge compared to standard aftermarket replacements. By utilizing high-grade magnetic steel cores, these units maintain stable voltage output even at high RPMs, facilitating more complete combustion and crisper throttle response. The kit includes specialized dielectric tune-up grease to prevent terminal corrosion and voltage tracking at the spark plug boot.
