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

High-Performance Ignition Coil & Iridium Spark Plug Kit for 2007-2008 Freightliner Sprinter

What it Does: A direct-replacement ignition and spark overhaul kit designed to eliminate misfires, restore lost fuel economy, and deliver a more complete combustion cycle in the 3.5L V6.

The Stock Sprinter Ignition Weakness

The factory W906/NCV3 ignition system, particularly the aging OEM coils on the M272 engine, is highly susceptible to thermal degradation and voltage leaks over time. Operating in the confined, heat-soaked engine bay of a commercial van accelerates the breakdown of the internal epoxy and copper winding insulation. This results in weak spark propagation, intermittent misfires under heavy load, rough idling, and diminished fuel efficiency. Standard or worn plugs further compound this issue by increasing the voltage demand on already stressed coils, leading to premature failure and potentially triggering catalyst-damaging unburned fuel scenarios.

The Engineering Solution

This OE+ replacement package addresses these thermal and electrical vulnerabilities by utilizing upgraded ignition coils featuring high-purity, durable copper wire internals and advanced heat-resistant epoxy potting. This construction significantly reduces internal resistance and thermal breakdown, ensuring consistent secondary voltage delivery. Paired with the included Iridium spark plugs, which require less firing voltage while providing a highly concentrated spark kernel, this kit delivers up to a 15% improvement in combustion energy and efficiency. The fine-wire iridium center electrode resists spark erosion, maximizing service life and guaranteeing stable ignition timing even under heavy payloads or continuous fleet operation.
