Ignition Coil + Iridium Spark Plugs for RAM ProMaster (2022-2023) 3.6L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2022-2023 RAM ProMaster (VF)

What it Does: The ignition coil and Iridium spark plug kit replaces failing factory coil-on-plug units and eroded plugs on the 2022-2023 ProMaster to eliminate engine misfires, smooth rough idle, and restore peak combustion efficiency under heavy cargo loads.

The Stock RAM ProMaster Thermal Breakdown Problem

Commercial duty cycles, stop-and-go fleet operation, and dense under-hood packaging in the VF chassis create severe thermal saturation. Over time, heat-cycling degrades the primary and secondary copper windings and internal dielectric epoxy inside the factory coil packs. This degradation leads to intermittent spark dropouts, unburned fuel entering the exhaust, and fault codes such as P0300 through P0306. Concurrently, factory spark plugs suffer from electrode gap erosion, requiring higher secondary voltage to bridge the gap and accelerating thermal breakdown of the coil.

The Engineering Solution

Engineered for high-duty commercial demands, this service kit pairs direct-fit replacement coils with premium Denso Iridium spark plugs. The coils feature high-grade magnetic laminations and reinforced epoxy encapsulation to isolate voltage and resist dielectric punch-through under high temperatures. The Denso Iridium plugs utilize an ultra-fine wire center electrode that drastically lowers the required firing voltage, creating a more stable, concentrated flame kernel inside the 3.6L Pentastar V6 combustion chamber. Premium silicone boots ensure dielectric insulation to prevent secondary voltage flashover.

Frequently Asked Questions & Fitment Warnings

Does this fit the VF ProMaster?

Yes, this is a direct fit for the 2022-2023 RAM ProMaster equipped with the 3.6L Pentastar V6 engine. Spark plug wires are not included, as this platform utilizes a direct coil-on-plug setup; verify your harness connector profile prior to installation.

Should I replace spark plugs and ignition coils at the same time?

Yes, servicing both simultaneously ensures balanced primary-to-secondary resistance and prevents excessive firing loads on new coils caused by worn plug gaps.

The RAM Commercial Standard

Payload and fleet uptime depend on reliable low-end torque delivery and zero engine misfires, ensuring your commercial van handles maximum cargo capacities without unforced downtime.
