Ignition Coil and Iridium Spark Plugs for Nissan Z (2023-2025) 3.0L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2023-2025 Nissan Z

What it Does: The Ignition Coil and Iridium Spark Plug Kit restores clean, high-voltage spark delivery across all cylinders on the 2023-2025 Nissan Z to eliminate misfires, stabilize idle, and maintain peak twin-turbo combustion efficiency.

The Stock Nissan Z Ignition Degradation

The factory VR30DDTT twin-turbo platform operates under aggressive boost pressures and elevated cylinder head temperatures. Over sustained operation, the factory coil-on-plug pencil coils suffer dielectric breakdown in the internal epoxy insulation and secondary windings due to severe thermal cycling within the compact RZ34 engine bay. Simultaneously, factory spark plug ground straps experience rapid electrical erosion under high cylinder pressures, widening the spark gap. This gap expansion strains aging ignition coils, triggering high-rpm spark blowout, intermittent misfires, ECU timing retardation, and lost throttle response during boost spool.

The Engineering Solution

This complete ignition refresh kit pairs six high-output pencil coils with precision-gapped fine-wire iridium spark plugs designed specifically for forced-induction thermal loads. Each coil housing utilizes reinforced thermal-resistant PBT polymer and high-grade copper windings to resist insulation breakdown and maintain stable secondary voltage output under continuous load. The included iridium spark plugs feature a laser-welded fine-wire center electrode and platinum-tipped ground electrode, lowering required firing voltage while resisting electrode rounding and carbon fouling. This direct-replacement package restores factory dwell response, directly referencing OE interchange numbers 224485NA0A, UF819, and 224485CA0A.

Frequently Asked Questions

Does this fit the RZ34 Z?
Yes, this is a direct fit for the 2023-2025 Nissan Z equipped with the VR30DDTT engine.

Do these spark plugs require pre-gapping prior to installation?
The iridium plugs come factory pre-gapped for OEM boost levels, though inspecting gap clearance with a feeler gauge prior to installation is standard practice.
