Ignition Coil & Spark Plugs for Ford Transit-150 250 350 350 HD (2017-2019) 3.7L V6

Direct-Replacement Ignition Coils & Spark Plugs for 2017-2019 Ford Transit

Restores proper combustion and eliminates misfires: This direct replacement ignition coil and platinum spark plug kit resolves common ignition system degradation in the 3.7L V6 Ford Transit.

The Stock Transit Ignition Degradation

The OEM ignition coils and spark plugs on the 3.7L Cyclone V6 are prone to significant thermal degradation over extended mileage. In the engine bay of the V363 Transit chassis, localized heat soak breaks down the internal coil epoxy resin, leading to micro-cracks and subsequent voltage leaks. Concurrently, factory spark plug electrodes wear down, widening the gap and forcing the coils to work harder to bridge the gap. This compounding electrical stress results in rough idling, noticeable hesitation under load, poor fuel economy, and eventual P0300-series cylinder misfire codes, especially when hauling heavy payloads or climbing steep grades.

The Engineering Solution

This comprehensive ignition refresh kit directly addresses these thermal and electrical vulnerabilities. The included replacement ignition coils feature an upgraded high-dielectric epoxy housing and heavily insulated copper windings to resist heat soak and prevent internal arcing. Utilizing OE-style female blade connectors, they plug directly into the factory harness without modification. Paired with platinum premium-grade spark plugs, the system benefits from a durable center electrode that resists erosion and maintains a precise gap over thousands of thermal cycles. This ensures consistent, high-energy spark delivery, optimizing combustion to restore factory throttle response, stabilize the idle, and maintain peak hauling capability.
