Ignition Coil and Iridium Spark Plugs for Infiniti Q50 (2016-2023) 3.0L

High-Dielectric Ignition Coil and Iridium Spark Plug Kit for 2016-2023 Infiniti Q50

What it Does: The Ignition Coil and Iridium Spark Plug Kit restores complete combustion chamber efficiency and stabilizes high-load ignition delivery on the 2016-2023 Infiniti Q50 3.0L.

The Stock Infiniti Q50 Dielectric Breakdown

In the V37 chassis, the twin-turbocharged VR30DDTT generates significant thermal loading within the cylinder head valleys. Factory coil packs (OEM 224485NA0A, UF819, 224485CA0A) frequently suffer from insulation fatigue and internal thermal cycling breakdown. Over time, heat soak degrades the internal epoxy resin, resulting in micro-arcing, secondary winding resistance drift, and boost-induced spark blowout under heavy load. Combined with factory spark plug gap expansion under boost, this ignition fatigue manifests as hesitation under acceleration, erratic idle, and P0300 multi-cylinder misfire codes.

The Engineering Solution

This direct replacement ignition kit resolves high-rpm spark blowout by pairing six high-energy pencil coils with fine-wire iridium spark plugs. The ignition coils feature premium copper primary and secondary windings encased in high-dielectric epoxy potting to isolate secondary voltage tracking. Matched with fine-wire iridium core center electrodes and ground points, this setup lowers required firing voltage, accelerates flame front velocity, and resists gap erosion under high cylinder pressures.
