Ignition Coil + Spark Plugs for Ford E-350 E-450 (1997-2017) 6.8L

Heavy-Duty Ignition Coil and Spark Plug Kit for 1997-2017 Ford E-Series (VN58)

What it Does: The ignition coil and NGK spark plug kit replaces worn factory ignition components on the 1997-2017 Ford E-Series to eliminate cylinder misfires, restore combustion efficiency, and stabilize heavy-load engine performance.

The Stock Ford E-Series Ignition Coil Breakdown

The VN58 chassis encloses the 6.8L Triton V10 inside a tight van engine compartment prone to severe radiant heat soak. Over extended mileage and heavy towing cycles, factory coil packs suffer thermal degradation of their internal primary and secondary windings alongside dielectric fatigue in the silicone boots. This deterioration causes high-voltage micro-arcing and intermittent misfires (DTC P0300–P0310), resulting in hesitation, rough idling, and poor fuel economy under heavy gross vehicle weight ratings.

The Engineering Solution

This comprehensive 10-cylinder service kit utilizes high-dielectric epoxy encapsulation and high-conductivity copper windings designed to resist thermal breakdown under extreme commercial duty cycles. Paired with genuine NGK TR55 (3951) nickel-alloy spark plugs, the package delivers consistent spark arc voltage, reliable flame front propagation, and seamless throttle response across the entire rev range.

Frequently Asked Questions

Does this fit the VN58 E-Series?

Yes, this is a direct fit for the 1997-2017 Ford E-Series equipped with the 6.8L Triton V10 engine.

What torque specification should be used for the spark plugs?

Torque the NGK TR55 spark plugs to factory specifications (11–14 lb-ft into clean, dry threads) to protect aluminum cylinder head threads.

The Ford Workhorse Standard

Engineered for commercial fleets, cutaway chassis, and heavy hauling, these ignition components provide the steady dielectric isolation and thermal endurance required for continuous towing and extreme duty cycles.
