Ignition Coil & Iridium Spark Plugs for Dodge Sprinter 2500 3500 (2007-2008) 3.5L V6

High-Output Ignition Coil & Iridium Spark Plugs for 2007-2008 Dodge Sprinter

What it Does: This direct-replacement ignition coil and iridium spark plug kit resolves misfires and poor fuel economy by restoring optimal spark energy to the 3.5L V6 engine.

The Stock NCV3 Ignition Weakness

The factory ignition coils on the 2007-2008 Dodge Sprinter, specifically those equipped with the M272 3.5L V6 engine, are notorious for premature degradation due to sustained engine bay heat soak. Over thousands of miles of heavy commercial duty, the original internal windings and epoxy potting begin to break down, increasing electrical resistance. This degradation leads to intermittent misfires, a rough idle, delayed throttle response, and a noticeable drop in overall engine efficiency. Furthermore, standard OEM spark plugs suffer from electrode wear under high-load conditions, causing poor combustion cycles and throwing persistent engine codes that can sideline a fleet vehicle.

The Engineering Solution

This upgraded ignition package is engineered to deliver a 15% increase in spark performance and energy transfer, ensuring complete combustion within the cylinder. The coils feature highly durable copper wire internals with superior thermal epoxy, designed specifically to withstand the extreme heat cycling typical of the NCV3 chassis. Paired with high-quality iridium spark plugs, the system provides a concentrated, stable spark at a lower voltage threshold. The fine-wire iridium center electrode resists spark erosion significantly better than standard copper or platinum, offering OE+ durability and extended service intervals. This robust setup eliminates misfires under heavy load, stabilizes idle characteristics, and ensures the M272 V6 operates at peak thermal efficiency.
