Ignition Coil and Iridium Spark Plugs for Dodge Magnum (2005) 2.7L

Direct-Replacement Ignition Kit for Dodge Magnum

What it Does: Replaces degrading factory coil packs and worn plugs with high-dielectric copper-wound coils and fine-wire iridium spark plugs to restore precise combustion timing, eliminate misfires, and stabilize idle.

The Stock Magnum Ignition Vulnerability

The 2.7L DOHC V6 operates under elevated cylinder-head thermal conditions that accelerate OEM coil breakdown. Over extended heat cycles, factory potting epoxy degrades, creating micro-fractures in the internal insulation. This causes high-voltage secondary leakage, intermittent spark blowout under load, and carbon tracking along the spark plug boots. Compounded by widening spark plug electrode gaps on standard nickel or worn plugs, the resulting higher required breakdown voltage strains the primary circuit, leading to hesitation, rough idling, and catalytic converter-damaging misfires.

The Engineering Solution

This complete 6-cylinder overhaul kit features reinforced coil-on-plug units built with heavy-gauge internal copper windings and high-temperature dielectric thermoplastic housings that resist thermal shock and electrical arcing. Paired with fine-wire iridium spark plugs, the assembly minimizes voltage requirements while maximizing spark kernel growth and combustion efficiency across the entire RPM band. The plugs feature corrosion-resistant nickel plating and thermal-resistant ceramic insulators to maintain consistent spark gap tolerances.
