6 High Performance Ignition Coil for Ford Transit (2015-2020) 3.5L Engine

Heavy-Duty High Performance Ignition Coils for 2015-2020 Ford Transit (Cyclone/V363)

Directly replaces deteriorating factory ignition coils to restore combustion efficiency, eliminate high-load misfires, and stabilize idle in Ford's workhorse V6 engine.

The Stock Transit Thermal Fatigue Problem

The Ford Transit engine bay environment is notoriously compact, with the 3.5L Cyclone engine situated partially beneath the cowl. This packaging leads to significant heat soak and limited airflow around the rear cylinders. Over tens of thousands of miles, the factory OEM coils (UF646) undergo severe thermal cycling. This heat degrades the internal epoxy insulation and primary copper windings, eventually causing micro-fractures in the housing. These cracks allow voltage leakage (arcing), which manifests as hesitation under load, reduced fuel economy, and the dreaded P0300 series misfire codes during steep climbs or heavy towing sessions.

The Engineering Solution

These high-performance replacements are engineered to exceed factory specifications by utilizing high-dielectric epoxy resin and reinforced magnetic steel laminations. The internal secondary windings feature a higher turn ratio to ensure a consistent, high-intensity spark even under increased cylinder pressures. To combat the Transit's specific heat issues, the boots are molded from high-temp silicone that resists cracking and oil penetration. By improving the magnetic flux and reducing internal resistance, these coils provide a faster rise time and longer spark duration, ensuring a complete burn of the air-fuel mixture for improved throttle response and long-term durability in commercial applications.
