Ignition Coil and Iridium Spark Plugs for Dodge Ram 1500 (2013-2018) 3.6L

Direct-Fit Ignition Tune-Up Kit for 2013-2018 Dodge Ram 1500

Direct OE Replacement: This complete 6-cylinder ignition kit restores factory spark energy, engine responsiveness, and combustion efficiency on high-mileage 3.6L Pentastar engines.

The Stock Ram 1500 Ignition Degradation

Under repeated thermal cycling and prolonged engine bay heat soak, factory coil-on-plug epoxy resin and primary windings breakdown over time. This insulation degradation causes micro-arcing, internal resistance spikes, and intermittent high-RPM misfires. Paired with worn spark plug electrode gaps that exceed factory clearance specifications, the stock system forces the powertrain control module to adjust timing, resulting in sluggish throttle response, unburned hydrocarbons, and compromised fuel economy during heavy load and towing.

The Engineering Solution

Engineered to exact OEM tolerances, these replacement coil-on-plug assemblies feature high-grade electrolytic copper windings insulated with premium dielectric epoxy to withstand high underhood operating temperatures. The integrated blade terminals and reinforced boots prevent voltage leakage, while the companion fine-wire iridium spark plugs offer superior erosion resistance, lower required firing voltage, and a stable flame kernel under demanding cylinder pressures.
