Ignition Coil and Iridium Spark Plugs for Dodge Nitro (2007-2008) 3.7L

Direct-Fit Ignition Coil and Iridium Spark Plug Service Kit for 2007-2008 Dodge Nitro

What it Does: Replaces degraded factory coil packs and worn spark plugs with high-dielectric ignition coils and fine-wire iridium plugs to restore cylinder combustion efficiency and eliminate misfires.

The Stock Nitro PowerTech Ignition Breakdown

The 3.7L PowerTech V6 engine bay subjects ignition coils to persistent thermal cycling and vibration. Over time, OEM primary and secondary coil windings suffer micro-fracturing in their internal epoxy insulation, leading to dielectric breakdown and high-voltage flashover. Coupled with eroded nickel-copper spark plug gaps, the compromised spark energy causes rough idling, intermittent cylinder misfires under load, unburnt fuel wash, and decreased fuel economy.

The Engineering Solution

This comprehensive tune-up kit features six direct-fit ignition coils engineered with high-grade copper windings and premium magnetic silicon steel laminations to deliver stable primary-to-secondary voltage transformation. Combined with six laser-welded iridium spark plugs featuring ultra-fine center electrodes, this package provides rapid flame-kernel propagation, reduces voltage demand on the electrical system, and ensures consistent combustion under high thermal load.
