Ignition Coil & Spark Plugs for Ford Mustang (2016-2017) 3.7L V6

Direct-Replacement Ignition Coil & Spark Plugs for 2016-2017 Ford Mustang

Restores lost power and eliminates misfires by providing a complete, matched ignition system upgrade for the 3.7L Cyclone V6.

The Stock Mustang S550 Ignition Weakness

The OEM ignition coils and spark plugs on the 3.7L Cyclone engine are prone to accelerated thermal degradation due to extended heat cycling in the S550 engine bay. Over time, the factory coil packs suffer from internal resistance buildup and epoxy breakdown, which leads to voltage leaks and inconsistent spark timing. Simultaneously, standard factory spark plugs experience electrode wear and gap widening under continuous load. This combination results in a cascade of drivability issues, including rough idling, hesitation under acceleration, unburnt fuel entering the exhaust tract, and eventual cylinder misfire codes (P0300-P0306) that trigger the check engine light and compromise fuel efficiency.

The Engineering Solution

This comprehensive replacement kit engineers out the factory flaws by pairing six platinum premium-grade spark plugs with six high-dielectric ignition coils. The upgraded coil packs utilize high-grade copper windings and high-temperature epoxy, significantly reducing internal resistance while maximizing voltage transfer to the plugs. This ensures a consistent, high-energy spark even under heavy load and high-RPM conditions. The female blade connector terminals match the factory wiring harness perfectly for a true plug-and-play direct replacement. Complementing the coils, the included platinum-tipped spark plugs offer superior resistance to gap erosion and fouling compared to standard copper or nickel alternatives. This matched setup promotes complete combustion, optimizing volumetric efficiency, restoring factory power output, and delivering a smooth, responsive throttle curve.
